The title doesn't make sense, or is it an extremely shortened version and it's a pun on the fact that it shortened the journey? Do you happen to know who the translator was?
I think I wrote this in a few hundred comments already. It's a little weird people make it about physical games, it's not really about that, physical games are dead on PC, barely anyone cares. It's about Sony locking people into the Playstation Store and having full control over prices. With physical copies you can buy them wherever you want and they usually go down in price relatively quickly after release. Digital store prices remain high for years after release and only drop sometimes during sales, but even then they drop to the level of physical copies. The other issue are used games, at the moment that only works with physical copies.
Dual licensing is a thing, so it's not 0€$£. Also if they didn't care for the license, it's probably also not crediting you for your work, so your software isn't even better known.
However, the company's gross profits dropped as operating expenses climbed far quicker than revenue, in large part thanks to AI-related capital expenses and other research and development
How can I prove that I have ownership over code I wrote myself, and that it isn’t copyrighted somewhere in the world?
As long as you had no access to that code and have some proof of that then that should be quite easy. I.e. you never worked for a company that claims copyright on something you wrote.
Developers also “generate” code and are also “trained” on code they written as freelancers or employees for others which is potentially copyrighted.
Then you need to do a proper clean-room rewrite with people who had provably no access to the original code.
It is the interpretation of the Judicial Branch of the United States government and the United States Copyright Office, the best authority on copyright law in the United States.
Codeberg is based in Germany where German copyright law applies, and German copyright law is quite different from USA copyright law.
You see, that is in your own words crap, they keep the good stuff for themselves.
