Yeah I do have a similar fear. Valve is something special. I tried to hate them, they're filthy-rich corpos after all, but I can't. Something of value will be lost when Valve finally succumbs to enshittification, which cannot be said of a lot of other big companies.

But my fear isn't necessarily about Steam. I have like 20-30 games in my library. Steam is simply the least shit way to play games you have/want to pay for.
