Oh damn, I always thought Apache2.0 will protect also the derivative works, but apparently I was wrong:
> You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, ...
> Beeper Clients
> Native iOS and Android clients (closed source forks of Element iOS and Android)
> Mac OS, Windows and Linux clients (closed source forks of Element Web/Desktop)
How can they make a closed source fork of an open source (Apache-2.0) project?

Any big company which cannot bear the costs of publishing code to github can just calculate how much it would have costed them, then send the code to me and I'll upload it to github for them and only ask for half of the price. Seriously, I'll halve your "cost". Because it is actually free and they are just bullshitting.
