You can want better. Wanting better is good, actually.
What you can't do (and expect to be taken seriously, anyway) is to take the best you got and give them crap for stuff that's not under their control in any way. They don't own the games getting delisted, so they have zero control over the delisting itself and they have better mitigations for this scenario than anyone else that make the situation actually safe for buyers. They may be "out of stock" of these games going forward, but nobody who bought them has to worry about not getting to keep them, which isn't true on most other platforms, Steam included.
For the record, I also disagree on how "we're seeing Valve's practices get better". They have their own set of priorities and while I like a bunch of them I dislike a bunch of them also. I don't need to pick sides here.
Case in point, I agree that asking for a patreon-style contribution is a bad move on GOG's part. I don't need to like that in order for me to like their choice to stick to DRM free content or to provide downloadable offline installers.
I genuinely don't know that I follow that explanation. For one thing, what reasons would there be to ban paid blind boxes, online or offline, while allowing outright games of chance with a monetary payout? In what world is a Magic the Gathering blister more of a problem (for a consenting adult, anyway) than an online casino?
But also, by the larger point you're making it seems like you'd be fine with a government saying "porn is banned for everybody because reasons" but not with "porn is banned for kids", at least in a scenario where that comes with age verification.
To be clear, I agree that both of those are... not good. I just don't know that I can wrap my head around the logic of thinking the more extensive issue is more acceptable than the alternative. You could argue that the porn ban is an excuse to add mass surveillance, but at that point we're not talking about the porn ban, we're talking about the mass surveillance.
Oh, and for the record, there is plenty of will someone think of the children regarding loot boxes. Both on its own and bundled together with a blanket assessment that gambling is immoral and/or illegal. It's actually a fairly close match to the porn issue, where concerns about children are being wrapped around a more targeted hostility around the concept from both sides of the political spectrum.
