1-The player won't care if there's a plan that impacts the dev, because they just want the game.
2-It won't impact the dev, since it's been rolled back to the pro version, and it was always intended to only hit top-income companies like Sega rather than indie devs, indie devs are very very unlikely to be affected by the installation fee.
3-The Day Before was not a steam thing, it was not a shooter thing, it was not an extraction thing, it was a Fntastic thing, a singular company decided it would scam its audience, which obviously doesn't mean all Steam games are scams.
So yeah, neither you or LSG should fear Steam, it should be every Indie's dream to put their game on Steam, there's better prestige, better support, and better tools at hand for release, meanwhile Itch and gamejolt are understaffed and filled with community volunteers rather than employees.
