This for sure. Making games easily accessible on linux have lead to a lot of people not having to deal with windows anymore.
It is the same effect as a kidnapping victim beeing grateful when someone comes to release them fom the torture rack. It is not strange that valve gets a lot of goodwill from their actions.
Would i sish more people did as steam does? Ofcourse! But none do, so we are grateful for steam. I think they saved pc gaming. And not only for linux.
for sure! steam liberated my machine from a windows dual boot partition. and made me go 100% linux all the time. gratitude is not really strong enough. it is more like when you have been captured, and then set free.
Factorio and Rimworld have kept me entertained several thousand houers each. Hands down the best value for money on steam. Even beat out free to play games ;)
