You're obsessed with the age of the game and it's irrelevant, completely. Valve never want TF2 to die, you will just have to get used to that idea.
Valve have made their development investment decisions and they're developing competitive systems for the game. It's happening, making stuff up about how no company with any sense invests development time in it's assets that still make it millions of $ a year (that would be really stupid obviously) doesn't make that go away.
They've stated in conversations with players designed specifically for public consumption that they want to make competitive a core part of the game with all that entails, with the expectation that they change the players who are currently pubbers into competitive players, and to create a stream ecosystem around that new skill based focus. Out of the mouth of Valve employees, updating the game to the current landscape. I'm going to take their word for it over yours.
Tournament wise it's possible that they wait and see how it does and historically that would be true, but what they did for comp TF2 in the past is from before the age of Twitch, before CSGO and before Dota 2. There is no reason to expect history to repeat itself as the landscape has changed so much and their attitude and experience as a company has grown massively in that area. There are good reasons to accelerate some competitive tournaments early to hype up adoption and grow that stream ecosystem, it's not hard to find another example of that happening right now: Overwatch.
Nobody is talking about million dollar tournaments or massive investments in events. Those are straw men, feel free to knock them down. What's happening is happening and it's indisputable, they're doing the work and investing in the game. Valve only own a limited number of major IPs and TF2 is one of them, it would actually be sheer idiocy to not invest in it to keep it relevant in the current gaming landscape, and fortunately that's not what they're doing.
I can't fathom why you'd write so much that's so obviously divorced from reality.
