I think the 'problem' is that reputation damage doesn't really impact Google's revenue. They get the overwhelming majority of their money from publishing adverts, with a significant amount on their own properties (search and YouTube). It really doesn't matter if a bunch of gamers decide Stadia screwed them over, or if some devs decide to avoid GCP because they killed Reader. Google still makes a staggering amount of money no matter what.
The only way Google killing products will ever impact the company is either if people have an alternative to Google Search (very unlikely) or if people stop wanting to work for Google because they see it as a dead end working on things that only last a few years (also unlikely because $$$ talks).
Google will continue to launch, run, and then kill products forever. I suspect that if you're at Google and you're not working on ads or something that displays ads then you're being paid to build something frivolous that won't go anywhere mainly so you don't go and work at a different company that could impact one of Google's cash cows. I'm a bit envious if I'm honest. That sounds fun.
