I made it a point a long time ago to never use any SaaS, PaaS, or cloud solutions from Google for anything important. First off, their offerings tend to be much more expensive than competitors. Second, Google tends to randomly drop features, services, and support for applications without warning whenever they want. Third, they don't have any actual support at all for anything. I use Linode for all of my hosting, and I can get tech support on the phone in less than 5 minutes even without the upgraded support plan. On top of this, Linode and DigitalOcean offer extensive community curated documentation for almost everything.
The above reasons are also why I don't use any open source software developed or maintained solely by Google. There's no guarantee that Google won't just stop maintaining it after a year or less. For a somewhat recent project, my co-founder and I evaluated using Angular2 for the front-end of our application. During our evaluation, we learned about Angular4. Knowing about what happened between Angular1 and Angular2, we decided to steer clear of the angular ecosystem. This decision also made more sense from the performance and ecosystem side of the argument. Most groups that develop open source software do their best to ensure that there is a well documented and simple upgrade path. Look at Django, rails, React, Vue, postgresql, etc for example. As far as I have experienced, Google products offer no such simple upgrade path.
To be honest, I'm not really sure what value Google is offering anymore. The only quality product from them I still find any use for is Gmail. Even Gmail has competitors that do Email better. I guess there's also youtube, but Google are kind of shitting that up as well.
I think the tech space needs to walk away from worshiping Google and Facebook. In all reality, the technical quality of their products is lacking and their entire goal is to lock both consumers and developers inside their own walled gardens.
