There is also Gnome Web (ex Epyphany), a browser that also uses the Webkit engine (as far as i know it’s the only ‘clone’ of Safari cause of this). It’s made for Linux (and Unix in general), though i heard somewhere they will make a windows version too. So we can broaden the choice to Chromium, Firefox or Safari.
According to the Safari (web browser) wikipedia article: «Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share», so yes.
Well, they actually can, but it is not magic, it might not work everywhere, but it indeed involves going against website demands. There is reader view in firefox (that parses a page and gives text and images), there’s ublock-origin that alone blocks so much adds and tracking that webpages load faster, there is ‘‘i dont care about cookies’’ (that automatically selects the cookie options on your chosen option), etc, stuff that could be implemented in the browser as options for the user just like privacy settings.
The people here already spoke of the option of medical tourism, can’t you look up that ? A colonoscopy is not some advanced tech, any decent hospital in latin america will be able to do that. Since you earn US dollars, you could research about making a trip to Mexico (possibly the cheapest option, because it can be done by bus or car), Cuba (possibly the cheapest too, because of the conversion rate and short plane distance), Brazil, etc for the travel, lodging and procedure (and even a little tourism too if you have the time and will XD ).
Wish at least Lemmy and Mastodon (the whole fediverse) were possible to see in Gemini browsers at least (i’m using Lagrange in case anyone wants to try), we are already immune to the technical and commercial obstacles of mainstream web, and are just text and image.
