You're projecting a lot on my comment. I spent most of my youth pirating CS and Unreal Tournament so no I don't care at all if people can do it from the comfort of their browser, besides such old games might as well be in the public domain as far as I'm concerned. I was just surprised that a website like this one managed to operate for more than a few days before getting shutdown for obvious piracy, that's all.
I guess there's precedent for Valve being pretty lenient with that stuff though, after all they embraced the Black Mesa HL remake when most other editors would've ceased-and-desisted it into oblivion.
