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.
I buy books, most of the times I read them. ebooks have been my salvation space wise, project Gutenberg saved me money wise, at least for the classics.
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.
The moment I realised that is the moment I quit both cigarettes and Meta products…
I think that the start was a PCMCIA or PC Card.
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. :)
