It depends how you look at it. A lot of products created by Google were good/high quality but were killed anyway. It's sad to see things being killed because they were not "big enough".
The ones that were not killed are atrociously shoddy and have been now for, you’d think I was going to say years, but it’s actually decades.
I feel like even their main products are shoddy as well. How can they recommend good, relevant ads if they can't even recommend good news articles, music, or videos? If I do any search in Google on a topic, even if it's just to get a tiny bit of info about that topic, Google decides I'm interested in it and will make recommendations based on that one, single search. Or sometimes I'll buy a product and start seeing ads for similar products later. That's not good targeting IMO.
