I’ve seen a lot of posts recently about FOSS. I’m not a programmer, so I don’t know anything about it. What is FOSS and does it have a big advantage over other software designs?
FOSS means Free and Open Source Software. Since English has two meanings for ‘free’ (one as in no cost, the other as in freedom) you’ll also see it called libre software because Latin languages differentiate between no cost (gratis) and freedom (libre).
Open source means the source code is available and required to be accessible. The Free part is you have the right to take that code and use it in other programs. Copyleft licenses like the GPL will require any program you use that code in to ALSO be licensed under the same license, giving everyone access to your code under the same conditions. Non-copyleft FOSS licenses like the BSD licenses do not require that, and allow the incorporation of the code in closed source software.
To give an example of the differences let’s use Apple. Much of OS X userspace is derived from BSD Unix, so Apple can use it and not release code. But KHTML, the KDE HTML Rendering engine they took to make WebKit, was GPL so they had to release their changes and allow others to do the same, which is how you ended up with Chrome and Edge also using and extending WebKit and now it’s basically the standard browser rendering engine.
FOSS is free open source software, which means it doesn’t cost money and you can use it for anything you like.
In practice this means you can download these apps and modify them or contribute to them, and you always know exactly what they do (for the most part). FOSS isn’t necessarily better than paid software, nor is it necessarily worse, but it is more accessible software.
Sync is ad supported or paid which some people are against, arguing it’s monetizing free content. They don’t like the ad tracking and I strongly agree with that.
But at the end of the day, if a developer wants to get paid to write software I’m in favor of it, it’s not like this is Google or some other large Corp, it’s a single developer building and maintaining Sync (though I think the lifetime price is way off the mark).

This is misrepresenting FOSS quite a bit. A lot of open source software is indeed this permissive, but not all of it. It’s important to refer to the license of each individual project because various licenses have different terms.
Some open source software may be free for personal use, but that license may not extend to other companies seeking to profit off their open source and good will. ZeroTier comes to mind as an example of this.
Further, other licenses like GPL only requires that you make your sources available upon request but you can require that your customers pay you to receive the product: i.e. RHEL. At the end of the day, FOSS means free as in speech, not free as in beer
It means that the source code is released and available and you can even build the code yourself. You can inspect it to make sure it’s not doing anything malicious or stupid (but more likely you can hope other people that are smarter than you will do it).
The only advantages it has really for regular end users are it’s free, and if it’s popular other developers will make apps that use it.

Free as in speech, not necessarily free as in no money exchanged. The GPLv3 explicitly allows commercial use to both the creator and third parties.
FOSS = Free and Open Source Software
Basically it means anyone can view the code and tinker with it/look for security failures/add features for themselves, etc.
