Re: Even MORE RANSOMWARE !
So much wrong here I don't know where to start.
First, Windows 11 runs fine without SecureBoot and TPM 2.0. They're pushing for it, but its not required.
Google: bypass tpm install windows 11
Online = Easily Hacked? I'm just going to walk past that. I'm sure you'll get on well with your bricks-and-mortar only bank, if you can still find one. Make sure you air-gap your ubuntu.
Windows (spelled without the childish Z) has its issues. But letting security flaws fester isn't one of them.
But I'm not sure you care about facts, so I'll stop with the thought that Free Software isn't free for enterprise, it still needs supporting. And that costs way more than the Licensing.
