As an Apple fanboy, I can easily say that Linus does
not hate Apple.
Linus DOES hate a lot of what Apple does; cases where they make things more unrepairable for no real reason, or various socio-political causes (like opposing Right to Repair or unions or whatever).
Regardless of that though, I would trust a Linus review of a new iPhone or iPad a lot more than I would trust a lot of other sites, because I know he's not going in with Apple fanboyism (the way I would, for example), and he gives reasons for all his opinions.
Fundamentally, he always comes across as principled. If he has an opinion he'll tell you, and he'll give you a reason. He'll admit that he was wrong when he (believes he) was wrong. He'll contextualize his thoughts so you can decide if this or that opinion is really relevant to your situation.
As far as I've seen, his AMD/Intel/nvidia opinion changes follow along with the facts. He's pretty PO'ed at Intel for basically just sitting around with their fingers up their asses for however many years, and only actually trying to make good products at good prices (and largely failing) when AMD suddenly stepped everything up.
nvidia makes great video cards, the best on the market, but he's not going to avoid calling them out for shady or anti-consumer business practices. AMD makes great CPUs and good video cards, but if they have a disingenuous benchmark or claim he's going to say something about it.
I dunno, no one is entirely unbiased, but from what I've seen over the years, I can trust Linus more than most other people.
