I think there's a bunch of different things conflated here:
- valve is generally doing a lot of good things, even things that basically don't benefit them at all
- gaben is a Billionaire with all the billionaire things
- people love valve for all the good that they do
- a bunch of people are pointing out that valve is still deeply involved in their gambling economy; in fact it seems to be a significant part of their profit margins
- there's no +/- on this. The good valve does doesn't displace the bad they do.
- a bunch of things can be true at once
- we should praise them for the good an criticize them for the bad
- people do not stop their opinion usually, it's just public focus that shifts to a new focal point.
What I'm trying to say is, from what I've seen most people are glad because valve is doing a bunch of good things while also being aware of the bad that they do. It's just more useful to criticize Microsoft or nvidia for doing net negative by a mile, and the public focus can only be so nuanced. Also people hesitate to punish valve for being bad, considering they might be one of the least bad big tech companies.
That's what I think anyway, and that would mean your opinion isn't unpopular just that the smaller parts of it interact in a different way than you describe.
