Seems a little complicated. The normal splash screens in Minecraft don’t have the logo, so you couldn’t just download the file used from the game. It either requires a screenshot per new version, or some level of image manipulation.

The problem is you’re gonna have to keep updating it with every Minecraft update.

You’re making the error of assuming conservatives have a status quo, or a party line, or any agenda other than being evil.

And with open source code, you have the right to copy and modify the code, and distribute your own copies of the original, or the modified code. Try that with closed source code and you’ll get a nice C&D shortly.

Most distros are the same under the hood. I’d recommend downloading different desktop environments. You can stay on Mint and keep all your files.
