It can create problems from a different angle, though. Google might lock your account for no reason for a week, without any explanation. If that happens, it's your problem if you lose your whole business after a week of downtime. Since it's Google, you can't even contact support.
This has happened to me a couple of times. Once, my account was locked for a day because their system flagged one of my servers for suspicious traffic. They locked all my servers, databases, and everything else, not just that one server. Another time, they locked a different project for a week. It actually took me a week to find a human who could unlock it; otherwise, it could have been even longer. I still don't know the reason for the lock.
So the main problem is that Google don't care about GCP at all, and threat paid customers in same way as free users (i.e., hostile to both)
GCP doesn't really have the Google problem of lacking support contacts. I've managed relationships with GCP for a couple of different companies now (from startup to mid-size enterprise), and in all cases I had multiple dedicated account reps that I could not only get on a phone, but frequently met with in person.
Maybe the story is different for very very small fish, but I had decent experiences with support even at the ~20-person company spending ~5k/month level.
My company spends maybe $4k/mo with GCP, and I have absolutely no idea who my "dedicated account rep" is. I did have someone contact me way back when, but after finding out we aren't VC funded they literally ghosted me.
I don't really enjoy being on GCP for that reason, but I need it for BigQuery, so...
After the last incident (with a week of downtime) I learned that they have a paid support, which you have to sign up in advance so it didn't work for us at that moment.
Now we signed up for it, though I still not sure how it works and how I supposed to contact them in case of an emergency. All I see they charge us something for that support agreement, hope I will never need it.
Not in my experience, unfortunately. The reps we got with GCP could give us advice, but no real powers to push stuff or solve problems, it felt more like L1 support. As described bellow, maybe it depends on a company size and/or a country.
