I cannot find any resources other than: OsmAnd is GPLv2, the API is MIT. I cannot find anything about the plugins, but that would only mean that the plugins are a mix of open and closed source, though the app itself is still open source.

standing to their documentation they have an exception to the GPLv2 for the Google Play app to be able (my guess here) to better process payments and such.

So to my admittedly poor understanding:

OsmAnd -> open source
OsmAnd on Google Play -> closed source but compiled from the FOSS code
Plugins -> YMMV depending on the plugin

Yet because OsmAnd and it’s API itself are FOSS I would argue that this is still the right community for the OP question. :)

the paid version is still Free and Open source. In this case free stands for Free as in Free speech and not as in Free beer.

Also none of the Free or Open source licences prevent you to sell the compiled software. Hell, most of the Open source licences don’t even prevent you to close the source code (Mozilla, MIT, etc.) it’s only the GPL and a few others that mandate that the source code must be made available on request…

Tracking stuff came as soon as you could communicate asynchronously with a server, really. It became widely known and a plague in the 10s but it started as soon as Ajax was available. Keep in mind that Google and most of the websites were free and ads driven almost from the start because that was the only way to create a critical mass of users.

some functionality of Tridactyl are disallowed becsuse of the plugin system Web Extension that Firefox uses. https://github.com/tridactyl/tridactyl#webextension-related-issues Qutebrowser on the other hand is built from the base up to be used like that.

If you have a specific problem you might find some answers in the issues on their GitHub (Tridactyl’s) or open a new issue…

Why limit yourself to seized data from the US only if hosted in the US if you can buy data from all over the world. In some respects that is a very smart move, in some other is deplorable and arrogant.

You are missing PPAs from the list even though it needs some attention on which PPA is being used. I used to use the when I was on Mint.

Carcinisation

The moment I realised that is the moment I quit both cigarettes and Meta products…

To be honest, the minimum you really need for a colourful website is just HTML and a dash of inline CSS, especially if you want to recreate that nostalgic early internet type of feeling. JavaScript is very much optional.

In my opinion you should start easy, understand how it all clicks together, especially HTML and then start building, and eventually rebuilding, on top of it after you have grasped the basics. Most people gets scared by HTML, CSS and JavaScript because they are usually presented together as if you couldn’t use one without the others, but you most certainly can.

Just my 2 cents.

high costs server side, poor quality of the videos, poor-ish internet connections, not enough powerful cell phones, etc. They were ahead of time. They achieved a decent success in the US but not much outside of it because of much of the reasons listed above.
