I guess my point was simply that "important enough" is a bar so high, virtually no one is likely to meet it. In my own case, my application was making just shy of $50k/yr when it was shut down without expressed reason, notice, or appeals process. Even in that situation, the lawyers said it wasn't worth it. Given the lost income, I was probably at the top 5% of people for a potential claim for damages, so what chance does the super majority of people really have if Google gives them the middle finger?
I'm really not anti-Google, and I hope I don't read like I am. In general, I do really like their services, technologies, etc. My sole complaint is simply that if you have a problem with them, they flip the bird and disappear. You have no ability to even try to reason with them. They are like the "Judge Dredd" of internet services. Once they decided on something (completely without any input from you), it's done and you're f---ed. They don't even bother to pretend otherwise, the "We are unable to provide further details regarding this issue" pretty much proves that.
