For starters just looking at growth in the past year is very favorable for them, but look at the past 5 and they’re the weakest aside from Facebook and by a relatively small margin. Almost all of their growth has been post-COVID, so it’s hard to say whether that trend will hold. Personally I expect them to return to the slower growth they had pre-pandemic as to me it doesn’t seem like anything core to their business has changed or is going to change within the decade.
Pixel has always lived in the shadow of Samsung and probably always will. Android hardware profit margins are slim. Chromebooks are doing well in education at the moment but they can’t break out of the low end of the market and each of their attempts to do so have failed. Devices overall are a mixed bag in my opinion.
Stadia isn’t very good, costs too much, has a mediocre game library, and given the massive development cost definitely hasn’t paid off and probably never will.
Nest is a business they acquired that’s continued to grow. This is definitely a win, but it’s a small one, and it definitely doesn’t pay for all the unsuccessful products they’ve built.
Custom SoCs are potentially promising, but it’s a specific niche and others are doing the same so that’s kind of a “wait and see” for me.
Their paid services don’t seem popular at all with the exception of gsuite & YouTube premium (which people mainly buy to get around annoyances like not being able to listen to audio from a video with your phone locked or switch apps on mobile while leaving a video running)
I expect a large chunk of that “other” revenue you mentioned is also Google Cloud which despite how hard they’ve tried is far behind it’s competitors and hasn’t seen nearly the growth that Azure in particular has had.
