Bubbling (something Google does intentionally to make the user experience better) is a much different and much less serious problem than the fact that Google offers inadequate customer support and has a heavy-handed banning policy
I'm not convinced it's less serious. Google's bad behaviour is serious precisely because it has total control of the memetic environment. I've never had a problem with Google that would have required customer support, but I am conscious that I make dozens of Google searches a day, and that my view of the web is exactly what Google wants my view of the web to be. That scares me more than the customer service I've never gotten.
"Bubbling" per se is essentially defined as that portion of Google's ranking algorithm that incorporates its opinion of you. The rest of it, the generic part of Google's algorithm, can and does reflect Google's desires as a company. The EU even fined them billions for it (specifically, for promoting Google Shopping over competing comparison services).
