With Google's questionable policies, buggy automatic decision-making and notoriously terrible support? Unless they're sure they can make their complaint go viral, the risk feels quite high.
Google has a long history of "oops, sorry we did $badThing to your account. We see now that it was a mistake. Thank you for going viral on Twitter/HN/Wherever our employees happened to see it" as customer/creator service. It's not an accident that they don't have appeal systems set up for most issues, it's a policy.

Would you risk your livelihood that some engineer wasn't tired when they wrote the interface? Remember: if something goes wrong, your account might be toast, and you can't talk to anyone that can help you. Unless you go viral.
If it's a liveihood issue, there's a 7 day grace period for anyone that's monetized before the account is shut down due to blocks. And if Google was widely ignoring counternotices there'd be lots of stories about it out there. I think I've seen one or two that were quickly handled.
