Samsung lets you disable Bixby fully. Users complain more about Samsung because Android users are not used to being forced by the device they paid $1000 for, it's a new experience for them, unlike Apple users.
I have the s20+ and tried to disable bixby as much as possible, but it cant be uninstalled (short of adb hacks that can get lost with updates), and even after disabling everything i could it kept popping up asking to update, though that thankfully stopped after a month or so of regular annoying popups. Probably going stock android next time
