Nerdzmasterz Is any of this accurate? I keep seeing this video pop up when I'm looking at stuff.
Yes, technically it is true, but it's mostly doom prognostication. Secure Boot and TPM are actually good and are not Microsoft technologies, even though they are pushing them hard with Windows 11. They stop hackers from getting deep into your system, which means it is unlikely they can compromise the boot process. You can also store information, like encryption keys, on the hardware, making it much more difficult than storing the keys on a hard drive. Of course, nothing is hacker-proof, but it's a huge hurdle to the really bad malware (like rootkits).
At least right now, on Linux you have access to do what you want with the keys. Including deleting the ones that come with the motherboard and adding/installing your own. I was able to enable Secure Boot on Ubuntu, but it was a little complex and required the command line. But it works, it's fine.
Though I do agree with the author's comments on computers being locked down and gatekeeped. This is the reason I will never use a macOS or iOS device (outside of development testing) because you cannot run the software of your choice. Though, even with Linux, it is not an anarchy. You can download the source code for an app, but you still have to abide by the license. And there are many licenses that are restrictive, like GPL, so it's not that you can just do "whatever you want". But it's much better then macOS and Windows, and certainly a world of a difference from mobile.
