Some of the complaints are valid, but their solutions are just as baffling as their targets.

It seems evident that they've either got a case of cognitive dissonance flowing out their ears, or they're dishonest in their motivation.

In any case, you're right, it is weird to point the finger at valve, especially since they've done so much for gaming as a whole;

• Proton: should speak for itself. Carves games out of M$'s gated community.
• Platform features: workshop, discussions, groups, guides. Fucking amazing.
• Family sharing: nobody asked for it, and it seems like a bad business move - Valve did it anyway.
• Index: great piece of tech. Too bad about the price tag though.
• Deck: fucking masterpiece. Blows Switch out of the fucking water.
• Support staff: fucking legends. I've had multiple interactions where they have breached their own policy to keep me happy,
• Privately owned: despite the incentives to cash out and make bank. They have a fucking spine, which makes them dangerous to other platforms.

This guy claims to be a long-time developer and modder, yet suggests Game Pass is better for preservation than Steam. If that’s their industry insight, no wonder nobody at Valve took their feedback seriously.
