IMHO, there's a fine line between constructive and destructive criticism. Freyland seems to me to be right at that line, so while I don't really have a problem with his comments (though they did get a bit personal at one point), I can see how some would consider them over the line and thus feel protective of a game they like.
However, if you want to see what
real flaming against a game company is like, check out the unfortunate scene on Taldren's SFC II forum!

You'll find a whole lot of hotheads spewing hatred that makes Jonathan's Posts look like love letters.

So, I'd suggest giving a little bit of extra latitude when deciding whether a post is a flame or just honest criticism - based on the SFC II Posts, if it's a flame you'll have
no doubt!
Anyway, here's hoping that the tone on the SE IV board remains civil as it has been in the past, with all participants trying to improve this game that has such promise.
Regards to all,
