Quick shout-out to Grayjay: An app to watch videos on any platform - reducing the power of individual services. The Software is open-source and can be found here: https://gitlab.futo.org/videostreaming/grayjay
I will test this out for myself and hope someone here finds this useful.
that's no excuse at all. This way they are restricting everyone's freedom.
Free software, or if you prefer, open source, is based on the principle that everyone can use the code for any purpose (some licenses have copyleft but that just requires you to share your modifications to the code).
A malicious actor will simply grab this app code anyway, don't giving a crap about the license and put ads on top. If they are a malicious actor after all, I highly doubt the license will stop them.
What the license is stopping are legitimate community forks. There's a fork of Newpipe that adds Sponsorblock support, for example, which comes super handy. If community forks weren't allowed, it wouldn't be possible at all.
Having a license allows them to go after the malicious actor with legal backing.
