If you’re referring to Sign My Rocket, it’s legit. I’ve been in the guy’s Telegram channel, Combat Footage; the pinned messages have more information, including when the actual website was launched (iirc, it all used to be done via Telegram messages). I believe the older pins explain how he’s working with a charity helping the army in Cherkasy. A friend of mine recently bought a signed shell as a birthday gift to himself. Most people will go for the shells since they’re smaller and cheaper.

Obvious content warning for the channel itself - as the name says, there’s tons of footage from the battlefield that is posted.

Yep, I had the same thought. I run Win10 on my desktop and PopOS on my laptop; I plan to keep running Win10 for as long as possible, but if this cloud-based nonsense is the future, I'm not hesitating to also switch my desktop to Linux. This stuff is so ridiculous.

It's like a fire that just keeps burning
