No cause they want to be able to prevent people from adding ads and tracking to the app and then redistributing it.
He talks about this in the announcement video.
I saw the video. Is that really against the FOSS philosophy? I imagine that you can’t do that with e.g. the kernel either.
The licencing they chose is a bit of a hack job, but I see the necessity. IMHO, it’s clear that they want to advance the libre software world.
The difference with Linux kernel is that it’s way more complicated to persuade someone who just likes the idea of it to install it, so there’s really no protection needed - if you’re installing a custom kernel (or more likely, a whole OS using that kernel) you probably know enough not to end up downloading malware.
That’s not so true about just providing “random” APKs.
It’s not Libre software. It’s source available, which is great for a commercial product, allowing people to compile it themselves, but the license is revocable at any time.
It’s not contributing to the open source ecosystem, so it’s not part of the libre environment.
It’s a good thing, I’m glad it exists, and I’m excited to see it spur libre development in the same vein. But it is not open source as the term is commonly used.
