Till they stop making money off skin/etc sales.

I will buy the explanation that the game is too old to continue to support when they stop adding new microtransactions every six months or so

As long as it continues being one of the top games on steam by online player count, and/or it continues to make them boatloads of cash?

I don’t think the age of the game is really relevant. If the game is active and you’re making money on it, you support it.

That’s precisely the problem; they continue to support the game, in the state that it’s in. Honestly, an appropriate move would be for them to officially discontinue support for the game altogether (even if that means not having a new IP to replace it with). This means turning off their official servers, and removing the ability to buy/sell inventory items on the Steam Marketplace.

Right now, Valve allows people to sell items for real money (which they take a cut from) in a game that is overrun by bots. They need to either fix the bot problem, or stop taking people’s money.

Up until they release the intellectual property into the public domain, alongside the source code and hosting tools.

Corporations are not to be trusted to maintain and preserve our culture. They have enthusiasticly proven again and again they are irresponsible and cannot handle this task.
