Why are there so few players in Tunngle (Arma 3)

Here I have been tormented by the question for a long time. Why are so few people playing through Tunngle.
It seems that at the time of the release of the game, everyone was complaining about the prices in the incentive, etc. And through Tunngle, you can play with all the latest patches and mods for free, and the people are one and a half digger. Here's how to understand it. Who to play with then. We'll probably have to buy litsuha.
