F2P = bad idea?

For some time now Team Fortress 2 is free to play. First it was relesed on Macs and now Valve give it or free to everybody. Is this a good idea?

In my opinion it is not. TF2 used to by game for skillful player that know how to play their role in team. Now newbie in this types of game Mac users and people that didn't want to pay for game are destroying the gameplay. I'm not saying that they shouldn't play, but they should learn how to play fist. 

But falldown of TF2 begin earlier. Just after soldier & demoman patch game started to be festival of people who got a lot of money. They were buying games just to get hats in TF2. Of course in valve poin of view it was awesome, but still for fans and recently gamers it was tragic. In addition not long after shop with all the items from game appeard. I know that Valve want's money but it wasn't fair for people who were playing hard and making achievements to get weapons and stuff.

Now Team Fortress 2 is game for everyone who wants to show off.  Just look at them...

For me TF2 died in that day.
