I think you do have a good point but the problem is the powerful greed driving decisions by individual companies.
For example, windfall and increased resources have not changed the buggy mess the SaaS games produced for the last 2+ years from EA. Individual users are now the test monkeys for games, which is why so many of them are either buggy messes on release or games stay in "alpha/greenlight" mode for years.
I think the best example of how to do it right is CD Projekt Red (Witcher series, Cyberpunk 2077) and Rockstar (GTA series, Red Dead Redemption, etc.). I really don't like how Rockstar games are SaaS and how they have a secondary login for cloud saves/purchases but DLC is free and there's no question about quality. And CD Projekt Red is doing amazing work with not only their games but also their supported store front GoG.
Another company doing it right is HumbleBundle, who let's you choose how much percentage goes to the publisher, storefront and developers.
Upshot is we, the gamers, get what we pay for and if we pay a company that encourages pure exclusives while blowing smoke up our asses claiming "it's all for the gamers!", then we only have ourselves to blame for the current state of the industry.
And 30% is very much industry standard among all players (Microsoft Xbox, Android apps, iOS apps, PlayStation, Steam, etc.). It was actually Microsoft that originally set that percentage more than a decade ago and every company followed suit. While it would be nice to dream of a lower percentage charged and with more cash going to developers, it is most likely going to take more than Epic/Sweeney's tiff with Steam/Gabe to change the industry standard.
To be clear, I'm with you, I want change, I want developers to have more cash in their pockets to create games but I also want games to drop back down to $45 for a triple A game, for games to not be exclusive on storefronts, and for DLC to be proper paid expansions. I'd also like for companies to allow modding on their games.
All of this is out the window though as long as big gaming corp is driven by greed and as long as gamers are okay with SaaS software/games.
We are in a worse and worse state of affairs as time goes on because we allow it.
