I'm with Nuku. The filter is on the wrong end. I don't care about swearing and the like, because I don't do that. But I can see no valid argument on the server side filter against a client side one. Sorry to be so dumb, but I can not see any.
For you concerned with bad language, client server allows you to filter whatever you like. I can't see the improvement on having HTC doing that for you.
I don't want to be misunderstood, I'm all for politeness, especially in an evironment (chat) prone to rude talking. But I strongly dislike having anyone telling me what I am able not only to say, but to hear, and what not.
Anyway, whatever, HTC has made its decission (funny to see somebody is entitled to state that has made the "right" decission), so be it.
All in all, the sense of having a nice playtime amongst adults has been eroded. Not big deal, I'm still a happy customer, but not the same feeling.
Cheers,
Pepino
