MS has nothing to do with it, except that BitLocker is much better than anything any Linux distro has to offer today.
It’s a piece of software with closed source code. I am aware that people can hide (and have done so many times) a backdoor or a mistake in source code so that it’ll be harder to find than many problems in binaries without source provided.
Still harder to audit.
You need to have the disk decrypt without user input, and you can’t have the secret with the user. (As the user is untrusted - could be someone stealing the laptop.) The normal Linux user mantra of ”I own the machine” does not apply here. In this threat model, the corporation owns the machine, and in particular any information on it.
Smart cards?
Hate RHEL all you want, but first take a look at what distros have any kind of commercial support at all from software vendors. This is the complete list: RHEL, sometimes Rocky, sometimes Ubuntu.
I know.
Basically, corporate requirements go completely against the requirements of enthusiasts and power users. You don’t need Secure Boot to protect your machine from thieves, but a corporation needs Secure Boot to protect the machine from you.
Sigh. Okay.
From the times when things were actually convenient to use. Buttons shouldn’t get random presses while the thing is in your pocket. Screens should be protected from scratches and dirt while in your pocket. It’s more compact when folded while in your pocket, while thicker, but an apple fits in my pocket, so thickness is not a problem.
Remind me what happened? Ah, yes, Steve Jobs went out on a stage and confused the hell out of millions of hamsters, telling them he’s brought them their Star Trek communicator. Well, that’s not what he said, but that’s what they heard and what he meant.
I’ve gotten used to making sure my hands are not sweaty when using a phone, and that it’s practically not usable when it’s cold and your fingers are not very precise, like when walking or when in a crowded place, and that you should be careful with that pocket to not occasionally unlock the thing and repost something personal into apartment building common WhatsApp chat, things like that.
But sometimes I recall that with a Motorola flip phone I could do everything with no loss of ability or speed in all these situations.
Not even talking about battery life.
Oh, that’s when.
