YouTube channel Orwellian Penguin has caused a bit of a stir by demonstrating a Librebooted T440P running Windows 10.
Not that anyone asked for it, but here’s my opinion: it’s better for someone to use free-software browser like IceCat, even if they are going to websites that use non-free JavaScript. In the same way, it’s better for someone to have a Libreboot BIOS, even if they are running a non-free operating system.
