I'm glad Google (and Apple and Amazon) got into the phone business, the camera business, the phone service business (Google Voice), the car business (Waymo) and the entertainment business (Youtube, Music, etc.)
The status quo was so awful (remember cable TV contracts with 200 channels you didnt want to watch?) and has finally improved with the tech giants putting pressure in cushy lazy incumbents.
Same for self-driving cars. Where were the efforts before Google and other tech giants go into the game? I seem to recall only incremental innovation for decades.
What I really wish is that they didnt botch some of these things (Google Voice is a great example of an amazing product with massive underinvestment (abandonment?) from Google.)
We also missed out on Google Voice, will miss out on whatever TV play they're making with YouTube.
To be fair, us Canadians are in the same boat. You can be literally a stone's throw from the U.S. and still not get a lot of features available. Voice was never available, Wallet took several years before it was rolled out here, YouTube Red isn't available here either. Hell, most new Home/Assistant features take months to arrive here too.
Except there's always going to be some critics, especially when you're talking about a corporation of Google's size.
There's going to be people concerned about privacy, corporate overreach, the nature of some of its activities (such as defense contracts).
You will also get various biased opinions, such as people who were hurt in some way by Google: rejected candidates or businesses that folded due to some Google service grabbing their market share.
Hell, even if Google religiously avoided all the above, you will still get some astroturfing campaigns by its competitors!
Negative commentary on a niche website like HN doesn't actually mean much in the grand scheme of PR. Check what the average person thinks about Google. Most likely you will find it quite positive. If you're looking for a company with serious image problems, compare to Facebook.
Getting into too many fields and ending up all over the place is bad management.
Executives protecting their turfs may indeed be a recipe to getting bad UX, but that doesn't excuse the fact that it's bad UX or that bad UX is all over Google. If anything the latter points towards more bad management.
And as you wrote, customer service has always been bad.
