Every 1-2 months when Chrome updates I get banned by their throttling mechanism because I their extension makes too many requests and they see "unusual traffic"

It can take 1-2 weeks to go away and be able to use it. There's no way to get in contact with anyone. Tried the Chrome extension email, support forums.

It's a good reality check. There's no real support behind it and it can go away just like Google Reader did.

I think the motivations behind it are laudable, but they should not be the answer to the actual problem.
