Naturally, it is their life and their right, but then what do they care about the Metro? Obviously, it is not interesting to them. That is, it turns out that we (the developers) for years have been hard and painful, with losses, trying to do something special, but a certain category of players believes that our work is not worth even a couple of minutes to install the launcher. It seems that people did not want to play, just waited for a reason to pour out their bile. On the other hand, the reaction of a certain category of players (onli torrents and all that) is hardly adequate. Yes, and such a move pulls the need to install an epic launcher, which could cause some inconvenience to the players, and therefore cause discontent.
This is new, which could cause rejection.
On the one hand, the withdrawal from the stim is ambiguous, so no one has done so sharply (as far as I can tell).
