FUNKeyttriuma good way to put it is that they are not trying to kill it but they are actively killing it as opposed to passively killing it
It's not that valve is "killing TF2", TF2 has always had a ticking timer of relevancy. The issue is valve at this point in time are pretty much the only people capable of resetting the timer. Issue is, the way they're handling things, they're making the timer tick even faster. Half-baked releases, slow confusing response times, seemingly disconnected decision making. These have always been prominent valve issues but they become even more apparent now more than ever with the handling of matchmaking and maintaining interest in the game.
That's exactly what I'm saying.
Rather than letting the timer go on normally, passively killing the game by not doing anything, they're taking an active approach to try and reset the timer. However, in reality, the things they're doing are actually making it tick faster.
I was just trying to say it in one sentence.
