Honestly saying that Steam killed physical ownership of games and citing HL2 is a poor example. Just off the top of my head Blizzard beat Valve to this with World of Warcraft. You could buy a physical copy but you couldn't play it without their servers. Keys were locked to a single account as far as I'm aware.

Ultimately physical size constraints lead to the demise of physical purchases. That said, Valve in theory has a set-up to allow us to retain our games even if they disappear one day. How that works or how long it would take to happen is a different story, but they do apparently have something like a kill-switch in place.

TF2 was certainly the first major western game to have loot boxes, but extremely similar gacha systems already existed before this. It would be disingenuous to blame Valve for this, they just hopped on the train.

MFN clause is really only an issue if it can be proven that it is in place for anticompetitive reasons, and Steam's rule is not completely inflexible. Also, if the copy is being sold without Steam integration, fine, I can totally see why you shouldn't need price parity — but if you were to sell a Steam key price parity is entirely fair since the end user is getting access to Valve's servers. Also if a developer sold a game for the same price with no Steam integration on somewhere like GOG, Valve wouldn't be getting any cut, the developer would just be making more money (though ironically with less feature integration, it's not like Steam doesn't add value).

On the flip side instead of acting like we said all of Valve's decisions were pro-consumer and cherry picking a few decisions that aren't, I can cite:

• Valve's work on Wine/Proton
• the open SteamOS
• repairability and part availability and compatibility for SteamDeck
• all of the features Valve adds to Steam and the improvements they're making over time (it has gotten better), Steam is arguably easier to use and functionally superior to something like EGS
• the community marketplaces and discussion boards that Steam hosts
• their work to support users on a variety of platforms with things like Steam Link and even cross-platform support for their utilities and games

It's really not like they do literally nothing that is pro-consumer.
