I think you've mischaracterised things a bit in your post - not sure if this is just because you're repeating what you read elsewhere? Anyhow, regarding the bullet points:
1. Google Wave was released an experimental consumer product, designed to combine the best of IM and email. According to the announcement, it was finally sunset due to lack of interest from the public. Personally, I was super excited about Wave - I even pestered an ex-Googler at the time to get me in on the preview. (I was in uni at the time). However, I had a lot of trouble getting other people to use it.
Did you personally use Wave yourself? Were you able to convert anybody else to using it?
Firstly - this is hardly apples to oranges. You're comparing a experimental consumer-oriented preview product, to an enterprise offering with SLAs. It would be like if we released a Star Wars game showcasing awesome new WebGL features - then decided to sunset it 12 months later.
Secondly - the project was open-sourced and then moved to under the Apache banner - an effort that in itself took significant engineering effort.

I'm not really sure what more you want?
In the case of Reader - this is somewhat personal, as I was a big lover of Google Reader as well. From memory, it was deprecated with around 12 months of notice, there were provisions for migrating/exporting all your data etc. It wasn't open-sourced like Wave, but there were reasons behind that (I can't comment). However, it was hardly the worst handled deprecation - and to be honest, the writing was on the wall for RSS for a long time before that.
2. You didn't provide any specifics, so I'm not sure what event you're referring to.
AFAIK, the only major price change was when Google AppEngine left beta/preview, and became an actual commercial product, and Google added SLAs, and other things etc:

The changes were announced at I/O that year (May), I believe, and the actual changes took effect in September.
Is that what you're referring to? Because even taken aside my Google hat, that seems like a fairly reasonable thing to do.
3. All of Google's enterprise offerings have support. I know, because I actually work in such a support team. For GSuite, support comes free as part of the product - you can contact us via email/chat or over the phone.
For GCP, there are commercial support packages available (https://cloud.google.com/support/) (similar to the AWS model).
> They've done it again and again. I'd say its the default way Google operates.
This is a pretty bold claim - can you cite any examples of this?
If this is something that personally affected you - please feel free to reach out to me. I can't promise I can fix everything, but I can definitely try to find out more for you, or see what I can do internally.
