I don't have anything against him, I think in the iPhone X case he might deservedly be lauding Apple, their phone genuinely seems good. But more to your point, concerning watches I remember that for months on his podcast he was dismissive of the then rumored/speculated Apple Watch form factor altogether, he thought that if anything it would be more like a fitness tracker, and obviously once it became reality he unconditionaly praised the watch and now every new year with equal praise he is saying that the new model should have been the first one... Time passing, more than being biased I think his real issue is that he has become incredibly lazy with his work.
