I had an issue where the domain verification system Google uses was broken. There was a backend issue on their side where the Google Webmaster Verification worked fine but their Cloud Run product couldn't read it. Rather than help me their product manager said that Cloud Run was a preview service so it was my fault for using it- and then he preceded to recommend another service instead, although that service was also in preview.
This is just one example of many. GCP is the only service I've used where product managers will straight up insult and lie to users, and they'll do it publicly too (following their accounts on twitter is almost hilarious for how rude they are). Unless your company has nine figures in revenue GCP will happily crap all over you.
