It’s a really good extension, but I’m also not going to complain if Valve wants to implement that sort of information directly either. More easily-accessible data to aid an informed purchase is never a bad thing.

You’re conflating. While I don’t disagree that Valve is soaking up money, and when it fleet-of-yachts money, it’s just as sickening as when any-and-everyone else does it. Where there’s a difference is in the ‘How’. While I have my problems with Steam, generally speaking, they offer a good service. They provide servers and bandwidth while selling games far cheaper than their closest competitors, by one means or another.
There’s also how they’re using that money as a company. Right now, I can think of three different lawsuits Valve is involved in just off the top of my head, all of which are fighting to worsen the hobby for gamers and Valve is opposing. Obviously, it’s in Valve’s interest as a game’s marketplace to keep gamers throwing money at them, but the ‘Why’ matters a lot less in this circumstance that the ‘What’. Even if it’s not the express purpose, Valve is the only company I know of that’s putting in any amount of effort to defend consumer rights in the gaming space. Everyone else with money comparable to what Valve has are too busy trying to exploit the market or diminish Valve’s share while providing nothing as close to as good as Steam.
News that has come out since your comment involving Valve includes an agreement with Facepunch Studios to make Source 2 available to public without any licensing fee under the name of s&box. While it’s obviously in Valve’s interest to increase the possible amount of games that will be sold on their platform, and Facepunch have done a significant amount of heavy lifting in making Source 2 both available and useful to the masses, that’s still Valve doing their part to make the gaming community a better place and provide an alternative to the (in some people’s opinions) over-used Unreal and (horribly untrustworthy) Unity.
As Zorque has said before me, Valve aren’t angles, but I truly believe Valve is bringing a net positive to the market, unlike any other company with comparable bank balances.

Same can be said for any entertainment media in a way. Tiktok (for those people) YT or even films. They’re all ways to spend one’s time, even if they aren’t direct competitors. For those who choose a balanced approached between all of them, there’s really only time left in a person’s day for one or two of these kinds of games, let alone their dwindling funds for everything else that is increasing in price.

I don’t like all the Checkpoint Charlie bullshit and got fed up with the side content before the main story was over, but the world in Tsushima was so well made that I had a good time in it - far better than AC: Shadows (that I didn’t pay to play, for the record) - and the combat system was fun. Yotei has a character that isn’t forced into the peg hole of a samurai and has a greater selection of weapons so it looks like it’ll be a fun time.

write the same sorts of things on game boxes
Don’t be ridiculous. You’re describing criminal property damage. Of course that’s neither okay, nor the same.
I’m sorry you feel the need to be dramatic about this issue, but Steam have provided adequate tools for the userbase to handle the problem, in my eyes.
I don’t recall suggesting Valve getting a free pass, nor downplaying the CS skin market being an issue. What I’m saying is Valve at least turns that money to some good, unlike its contemporaries in the veiled gambling space.
