It gives me a somewhat unique perspective where I'm happy to give them lip when they need it and they have at times and they also ask for my input fairly frequently. In my opinion they are all in on GCP and it's definitely going nowhere but up. They've been on massive hiring sprees and it's to the point that when I visited them at the Googleplex a few months ago a bunch of their campus buildings were now labeled as Google Cloud buildings.
Obviously logos can be removed and maybe it will say Android/Allo/whatever in 3 years but the team is incredible and they seem laser focused on growing the platform. You can go through their blog https://cloudplatform.googleblog.com/ and the improvements they're making and the pace at which they're making them is pretty great.
I've used them for ~4 years so I've definitely had frustrations, especially prior to them reorganizing their Support/Account Management structure about 6-12 mo ago (I do k8s so I interact with this side of things as infrequently as possible).
This is a huge money maker for them and I think they're doing a great job albeit they still need to focus on their soft skills (support, billing pains, etc).
I have migrated a few companies from AWS to GCP and they've all been happy. If the day ever comes to leave GCP I have no problem making that call; I'm not handcuffed to them. Hopefully they just continue to improve.
I must stress out however that these are just my thoughts based on information from Internet, because I don't have extensive experience with either, so I might be wrong.
I was impressed.
Just got on the Silver plan with Google and only had one support ticket so far, but they got it resolved. Haven't really needed to push it yet, but we will see what happens.
And that's before you even get to your legitimate concern about Google's long-term commitment to any of their offerings.

Other commenters asked if they still had jobs after saying that.
