A major downside of any service once it becomes too large is that the overall complexity introduces lower reliability. From Google's perspective perhaps each rule and feature makes sense, but from a customer perspective, there might be too much risk of who-knows-what issues coming up. I don't think this is limited to Google. I miss the older, less complicated versions of most bigtech services; Facebook, Instagram, Google, Amazon, etc. Even looking at Vercel's project settings the other day I found myself thinking "hmm this is getting a bit unwieldy."
Perhaps if a company is providing a service that might be considered critical (e.g. primary email address / identity provider), then there should be regulations about the level of customer support, especially some sort of human response SLA.
It just doesn’t make sense; they have so much money they are one of the few that can actually make slightly less profit and have good customer support. But they choose to treat everyone like a robot & allow scam ads
