Totally agree with you there, as much as I love to hate non-transferability, revokable licenses, permanent VAC bans on accounts that got hacked, I still find Steam the most convenient path to "owning" games in one place.

The Linux work done for Steam Deck is fantastic and I do credit their efforts with inspiring others to work on similar projects that extend and complement what Valve achieved. Much of the hard effort did go into Windows games on Linux before Valve looked at it; everything the WINE project, Codeweavers did, gaming via Lutris since 2009, however Valve have definitely been a force multiplier.

Trust is earned and I think Valve are doing pretty well on that front, especially when you look at the differences to other PC stores, Ubisoft, EA, and to some extent Epic. GOG and Itch are very different beasts.

To some extent I miss the time where Steam was totally curated, you had to make an impact to get your game on the platform, back before it was a free-for-all of shovelware and low-effort slop. Occasional controversies aside, at least on Steam the tools / marketing funnel are there to keep the popular games at the forefront of the store whilst also being fairly open to allow devs to publish without being the chosen one.

Is there a danger of doing to games what Spotify has done to music? Maybe, but I reckon the super deep-discount sales have calmed somewhat and are happening later in game's long-tail part of the lifecycle or used as promo for sequels.

There are plenty of publishers that choose to mainly avoid going that route, often the traditional established publishers with console outlets they don't want to cannibalise, for example Sony and Konami.
