Self-hosted Gitea or Forgejo. It’s pretty easy to host, and if you’ve got a reliable Internet connection and an always on computer, you can host it from home without too much effort.

IANAL (and likely neither is anyone here) - and I think the answer would be “it depends” on other details if you asked a lawyer to make a decision on what you’ve shared. So I think that is the only route if you can’t get YouTube or the blogger to do the right thing.

Some relevant things this might hinge on:

• Is the person posting this doing making videos as a business venture - e.g. by making videos that they hope to profit from (e.g. by including advertising in it, or through YouTube monetisation)? If this was done as part of a business, that could make a big difference (generally businesses are held to a higher standard).
• Which country did this happen in? Laws are different between countries.
• Did they deceive you in any way to get you to do what they wanted for the video?
• Are you a public figure in any way (prior to the video)?

Some potential causes of action that your lawyer could consider if they apply:

• Misleading conduct - if they used deception in the course of their trade.
• Fraud - if they obtained valuable consideration (your video performance) through deception.
• Privacy Infringement - if they processed (including collected) your personally identifiable information (e.g. including images / videos of your face, or the identifiable sound of your voice) without consent or another lawful basis / denial of right of erasure. Some of this could apply to Google too - you might be able to submit a Right of Erasure (right to be forgotten) legal request, and at minimum they might need to blur your face and mask the audio so you aren’t identifiable.
• Copyright infringement - potentially what they recorded counts as a performance and you have a copyright interest in the video. Another one that could apply to Google and be used to take it down.

Tip for increasing the life of your next battery:

Li-Po batteries degrade far faster when their charge level is at the levels the manufacturers call 0-15% or 85-100%; the exact minimum and maximum charge levels are a manufacturer decision that trades off total battery capacity when new against battery life. Manufacturers make the decision by thinking about what is most profitable for them, which is the biggest possible advertised (brand new) battery capacity, while dying quite fast (within a couple of years) to sell more, but not so fast consumers can claim it is faulty.

So they will happily make the battery last 1/5th of the life it otherwise would, for +30% brand new battery capacity, even if that 30% will be gone in a year of typical use.

Those decisions are aligned to the manufacturer’s interests, but they are seldom aligned to a consumer’s interest. Most consumers would be better off with 30% less battery capacity, but a phone battery that lasts 5x as long - many people for example charge every day, and only get down to 80% or something anyway.

The way to re-align to your interests are to: stop charging above 85%, and shut down at 15% instead of going down to 0%. You can do this manually, but it is a real pain; you can’t just plug it in, and leave it until it is charged, you’d need to micromanage charging. Some more responsible manufacturers (e.g. some Samsung devices) have features that will do this for you if you set preserve battery mode. Others, including Google, however, really don’t want you to do this, because it hurts their sales. They don’t provide standard APIs available to unrooted devices that would allow apps that do this.

If you are willing to root your device (and ideally install a third party Android distro like LineageOS), you can install ACCA (https://f-droid.org/packages/mattecarra.accapp/) on a rooted device, and set it to stop charging at 85%, and shut down at 15%. This will increase your battery life very significantly, and drastically slow the decline in capacity you’d otherwise see. Unfortunately, many manufacturers hate people taking control of their own devices this way; Google has unfortunately convinced major banks etc… to use their so called “Play Integrity API” to check that your device is “secure” (where secure is defined by Google as including a phone no longer receiving security patches, with known vulnerabilities that let someone trivially install a keylogger over the wifi, but excluding the same phone rooted by the owner, with a highly secure up-to-date LineageOS install, with extra security software like firewalls that stock Android wouldn’t allow, and with ACCA installed; it’s almost like “secure” means toeing the Google line, and the banks have been conned). There are sometimes ways to pass the Play Integrity API checks even when rooted, but Google is constantly battling users to try to break them. But it might be worth it for better security and battery life.

Generally speaking optometrists measure the core measurements of how your vision is and make the prescription.

However, to make glasses as well as the prescription they need the interpupillary distance (IPD); how far apart the pupils in the centre of the eyes are.

The IPD rarely changes much / at all in adults (so saving for certain conditions, once you know it you could keep using that value), and measuring it is not that hard if you have another person to do it (read how to do it properly on the Internet).

I don’t know the law in Canada around what they have to disclose. I believe Canada has privacy legislation that says that people have access to private information about them held by companies in at least some cases, so that might be something to look into, and then request all the information they hold on you if you ever need the information again.
