Louis Rossman: The best way to watch online video; my yearlong project is finally done!

That's their goal. They have good intentions. But it also means no commercial use.

You can't do "Hey, can you add this feature to this app, I'll pay you" or "Here is much improved version you can buy from me" or "We give you paid support and help for this software for your company". Eventually all improvements bounce back to original creators anyway, see: vital paid Wordpress theme ecosystem, most of them being GPL licenced.

With project getting bigger such restriction can be almost as bad as with propietary app. Like, imagine Linux kernel but only with Linus Torvalds having right to sell computers with it or offer any services making money.

You can not modify the source code.

you are not entitled to use or do anything with the code for any commercial or other purpose, other than review, compilation and non-commercial distribution in accordance with the terms of this license.

"review" means to access, analyse, test and otherwise review the code as a reference, for the sole purpose of analysing it for defects.

He accidentally sent people to a Newpipe clone once and that's why they should have the right to kill your license at any point in time for any reason or no reason at all.

That's only half the reason, let's not forget opposition lobbyists abusing unidentified loopholes in his initial R2R drafts, which are very costly to rectify later both time wise and monetary wise, even if at all possible. The mindset of companies screwing with you is probably not something that is easy to shake off, especially encountering it each day fighting serialisation and other rubbish just to repair someones macbook.

While not ideal, I respect his decision taken with the license chosen, even if it's against the spirit of what most people consider to be open source.

The organisation behind the app, FUTO, wants to take control back from companies and put into the hands of people, and while we can make the argument that FUTO are being hypocritical by keeping the keys to the castle per se, they have delivered an app that puts control back in our hands - removing the need to have a separate youtube, patreon, nebula and soundcloud app, alongside others, where you can follow individual creators easier on the platforms where you financially support them.

It won't appeal to people who just want to watch YouTube without ads (go NewPipe, Revanced etc..) or staunch FOSS supporters, both of which are seeking other ideals from their media consumption apps of choice.

The kind of people who will be using this app the most right now IMO will be Nebula and Patreon users, this app is like a dream come true compared to the official ones

Technically open source in what definition? Not by Open Source Initiative definition (https://opensource.org/osd/), not in Wikipedia's definition (https://en.m.wikipedia.org/wiki/Open_source)...

Public code on GitLab does not mean open source in the same way public video on YouTube does not mean Creative Commons.

There is a difference between open source and source available...

Quite informative. Quite unfortunate.
