Please note that Germany has (compared to other EU members) quite strict and company-friendly protesting laws.

Such protests may be even considered as political protest (Politischer Streik) which makes them not illegal per se but could be illegal. https://www.bpb.de/themen/medien-journalismus/netzdebatte/219308/ein-bisschen-verboten-politischer-streik/

Hi, the user https://lemmy.comfysnug.space/u/Spectacle8011 posted an answer that you probably will not see:

The only thing I’m trying to prevent is someone taking the entire project, changing some strings and icons and releasing a paid Android version based on my work.

If you released your program under an open source license, they wouldn’t even need to change anything. They could simply republish your program unmodified for a price. Open source is fundamentally incompatible with restricting commercial use because it means surrendering your monopoly over commercial exploitation.

One way you could restrict this is by trademarking the name you publish your program under. This way, no one will be able to publish a version of your program with the same name, as they would be violating your trademark. The good thing about this is that trademarks have nothing to do with copyright and so are fully compatible with open source licenses. The bad news is that someone could always republish your program under a different name. If you’re primarily concerned about users confusing another program with yours, though, trademarks are a great option. You should register a trademark for the name anyway…before someone else does.

I don’t have a particular license to recommend that prevents commercial redistribution, but you appear to be looking for a “source-available” license. You might need something custom…every program I’ve heard of that is source-available has their own custom license (Futo Temporary License, the TrueCrypt license, Microsoft Shared Source Initiative, etc.) The closest thing I could find was the Commons Clause. I know very little about it, though.

I will do so :)

Maybe its because I am tired but I don’t get it, what does this mean?

Nope this is name is already taken:
