And because of Bitlocker, their encryption is worth nothing in the end.
> if these people were using Linux, their laptops wouldn't be encrypted
Maybe, maybe not. Ubuntu and Fedora both have FDE options in the installer. That's objectively more honest and secure than forcing a flawed default in my opinion.
No, it's worth exactly what it's meant for: in case your laptop gets stolen!
> flawed default
Look, in terms of flaws I would argue 'the government can for legal reasons request the key to decrypt my laptop' is pretty low down there. Again, we're dealing with the general populace here; if it's a choice between them getting locked out of their computer completely vs the government being able to decrypt their laptop this is clearly the better option. Those who actually care about privacy will setup FDE themselves, and everyone else gets safety in case their laptop gets stolen.
If my laptop gets stolen and it's worth something, the thief will wait until they can crack the management keys. We see this with corporate-locked laptops and Macbooks, iPhones and Androids, and other encrypted curiosities that get cracked at a lab in Tel Aviv for pennies on the dollar.

This line is equivalent to forfeiting your position so I don't even know what to argue over anymore. I do care about privacy and I have no idea who you're arguing in-favor of.
