Win+P allows you to quickly change how your windows works. Win+K brings up the menu to connect to a wireless monitor. Win+L will lock the screen. Win+R will call the “Run…” window.
KDE Plasma also inherits a lot of the shortcuts Windows has. AFAIK MATE/Cinnamon do also share some of the keybinds, but for some reason they use CTRL+ALT instead.
Also fun fact: the Windows key is also called the SUPER key.
While I have no idea about legality, it is quite obvious that X/Twitter is not really run as a company run as a public communications platform, but rather as a fever dream of Musk.
Especially the Eli Lily Co. disaster should’ve been a wake up call for X of how much harm the fake checkmarks can bring, yet nothing was done. Most likely because Elon Musk didn’t care. He basically runs it like it’s how little service that he fully owns and controls with full disregard to anything but his own vision.
Therefore including his other businesses makes sense, as the fine that is only based on X’s income would probably be negligible in his opinion, as he runs it on a loss anyways. Only bigger fines would actually have any effect in my opinion.
