But as I said before, Valve has done questionable things with their recent events and people didn't like those, though I don't remember this amount of backlash, but there was, and I recall Valve employee on twitter got upset and wanted to enter the discussion and defend it (Dota event).
Nemesis Assassin was a pay-to-play event. Someone in the match had to own a ~€30 arcana to activate it, plus other conditions
TF2 duck hunt was again pay-to-play, where if you paid €5 you got a personal stat tracker how much ducks you collected or killed whatever. I think Valve later changed the label to "pay to give money to the community" (it was a community-made update). People were pissed for that and other various reasons.
Operation Vanguard had a cooldown timers assigned to missions. After completing two you had to wait x amount of time do another again, unless you paid for it and the timer went down to zero.
And now here we are again.
This is a dangerous path Valve is going down, and people keep enabling them.
