I don't think using DRM makes a company evil, unless the DRM is so intrusive it screws with the rest of the system (Sony rootkits, Denuvo, etc.) It's just a reality of digital marketplaces where piracy is rampant. Lootboxes and always-on servers actually kinda help with that, at the expense of truly being a subscription and not ownership.
I know HN skews wanting to "own" games, but that's just not a big deal to most gamers. Physical media and DRM-free have always competed with Steam and GamePass and uPlay etc, but the latter are increasingly popular.
Countries are free to have their values, of course, but regardless, I don't think the presence of lootboxes in a couple games overrides all the other good Valve has done for the PC gaming community.
Other companies can (and do) implement loot boxes too. Fortnite's are much worse, being pay to win (in its original Save the World coop mode, not the more popular Battle Royale mode), but Epic's game store and exclusivity policies are much worse for the community. Activision, EA, Ubi, etc have similar lootboxes, often with similar DRM, but without any of the good of Steam and the customer focus of Valve.
Those are industry wide problems that probably should be resolved with regulation. But that doesn't make Valve a good or bad company, IMO. Of course others can disagree.
As for parents and kids, yeah, it's another discussion, but sounds like the same old thing about video games ruining kids. Whether it's Wolfenstein and violence or lootboxes or TikTok addiction or whatever, it still comes down to parental guidance. Its not an excuse, it's just a reality that kids grow up with way more technology and marketing than in the past, and that's a cultural issue way bigger than any one company (or government, for that matter). That's not on Valve.
