The ones who blindly believe their games are safe just because they're Steam, yes. Gabe has shown to generally be on the side of the gamers and the free market (free as in choice), but it's foolish to not be concerned about what happens in a Post-Gabe Steam landscape.

While Steam is leaps better than the walled gardens that are loudly pushing for full monopolies now that the masks are off, it was still massively controversial back when it launched and the concept of a wholly digital library was uncomfortable for a lot of people. Those concerns only went away once DLCs were shoe-horned into every game being released in the late 00s, normalising the concept, and have now resurged thanks to Sony showing how happy they are to delete digital libraries that were labelled 'purchase' and 'buy' at the time of sale. Twice.

Short of GOG's approach of giving the full executable with no DRM requirements and things like the recent mandate in China to be able to pass on one's digital library, digital holds no value and has little difference from throwing money in a dumpster fire. At the very bare minimum, there needs to be legally-mandated full-disclosure agreements at the time of sale to inform the customer of how long they're renting a product for. Not some nebulous warning of "We can remove this from you at any time of our choosing, with barely a lift of our finger and with almost no warning or avenues for compensation". That is the line of theft and anyone who is supporting it is not only fighting against their own interests, but actively screwing over everyone else too.
