I don't recall these being "beloved". This sounds like a troll to me.
Sure Intel do FOSS graphics driver development, but I doubt they've ever been beloved due to their constant scandals (ME and Meltdown recently, and further back there's ClassMate, Itanium/Itanic, etc.)
AMD promised open drivers. We're still waiting.
ARM systems are usually locked down and full of blobs (e.g. for graphics, etc.). Plus ARM don't make chips, they just sell licenses to their designs to third parties, which is completely anti-FOSS.
Google do support a lot of FOSS development, but their online monopolies and spying infrastructure have always kept people suspicious.
Apple has a habit of turning liberally licensed FOSS into proprietary software (e.g. OSX is based on Mach and BSD, Safari is based on KHTML, etc.). Their mobile OS also requires programs to be signed, and they charge a $99 fee for developers to get a certificate.
As far as I'm aware IBM have historically been the enemy. They certainly pushed Linux forward around the millenium, but since then I've not come across them outside bloated "enterprise solutions" that I doubt many in the FOSS world would consider relevant.
No, we aren't. AMD's promise was fulfilled quite a while ago. They officially contributed, and work on, a FOSS driver for the Linux kernel, and also for Mesa. One of their devs is one of the most active Mesa committers this year alone.
AMD are more committed than Intel is, it would seem, given that AMD's drivers are far better quality than Intel's.
ARM is an open company? When did that happen? They still don't provide architecture reference manuals for download (unless you are customer), unlike AMD or Intel.
