You're overthinking this. As I said in Rule 1: "
Critiques on products are okay, but be cool about it." "Even handed and apropos" fall under the umbrella of "
be cool about it," so you're fine.
There are lots and lots of post critical about products by Spitfire and just about every other company here. (Except Realitone, of course, which would get you banned immediately!
) Totally fine. Honest opinions (both good and bad) about libraries is probably the biggest function of the forum. In fact, it's how the forum got started. (Check out the masterfully written
"A Short Forum History" post on the
Portal Page.)
The purpose of the new rules isn't to stop critiques, the purpose of the new rules is to get people not to be jerks when they do it.
