I wish Valve used their weight to cut down on the DRM, online activation and micro-transaction bullshit.
They had original steam drm that people railed against at the begining.
Valve and Gabe are not the second coming people make them to be. They are the least shitty maybe, but man... the bar is really low at this stage.
Then i'd bet if they gave the publisher statistics on how many people never see their game because it contains denuvo or a 3rd party launcher you'd see meanigful change, and if not then at least the store is nicer for the steam customers who care about it.
MTX and Always-Online BS is also down to the individual games, nothing Steam can do about it realistically.
