I never said they do, I said they sell "GCE VMs with years of uptime" i.e. "just pay for VM and let us worry about maintenance, you can simply assume it works for all intents and purposes".

But, the kind of stuff that people are worried about is not VM uptime. It's "honest customer being banned with no recourse and having entire livehood destroyed". You don't hear Google bragging that "we have an SLA of 99.9% service to honest customers - we only destroy 1 out of every 1000 businesses that choose us!". You can bet that their SLA there is 100%, even if it's not achievable, 100% is absolutely their target. Just like the target for Facebook is 100% security, and you won't hear Zuck bragging that "we are 99.9% secure, we only leak your private data once every 3 years!".
