The general instruction I got was you couldn’t use revocation as a threat to 
keep customers from switching CAs. That was pretty clear from Ryan. Other bad 
actions were implied as prohibited, like revocation just because a contract 
terminated. Like I said, I’d love to see it written down as an official policy 
as the bounds and applicability are hearsay.

In so far as it's not really a written rule, I wonder if what was described 
here would really qualify in the same way?

This sounds less like it was about a customer amidst migration and more like it 
was a "sell long validity cert on `credit` and collect payment over cert 
lifetime".

Although Ryan Sleevi isn't with Google now, I assume that policy still stands. 
You can report bad acting CAs there. See

It would be nice to see this rule actually canonized somewhere instead of it 
just being several old discussions on MDSP.

I suppose so. It's dissapointing, it allows CAs to use revocation as a sabre to 
rattle to keep subscribers acquiescent.

Sure, "protection racket" is such an ugly term :)
