Also not totally fair because Google has provided a ton of free web apps and Amazon hasn't, but I think it feels more personal when Google removes something that provides a daily quality of life improvement for many people.
I could compare it to a company like Cloudflare, who do offer lots of different public, free services (even if their market is different) and don't seem to have shut anything down.
Maybe not the best analogy either, but the problem is no other company has the kind of breadth of free public consumer-facing services that Google has, so no analogy would work. On one hand that could be a defense, by saying what Google's doing is unique and risky so sudden cancellations are to be expected. But on the other hand who knows how another company might handle a similar situation; we have no way of knowing.
Since you are comparing to AWS, do you have any source for apparently lots of products that were killed in Google Cloud?
