I think difference is EA is more a game company so people see a game they like then judge the monetization because its a full priced game that turns out to have f2p monetization.
But, Valve is more judged for its experience as a launcher and less for its games. So with the launcher itself being the draw things like Valve game lootboxes can be something people are completely unexposed to as they play other games.
But, EA is still at a stage where the products that receive the most visibility are their games, and the launcher and services side so underwhelming it isn't a selling point.
Its like Costco versus a company known for its pizza. Costco is a warehouse store people love going to that happens to sell pizza, but is judged on multiple things that draw them there over other stores as opposed to pizza. A pizza company is just known primarily for its pizza so judged on the quality of their pizza.
Gambling mechanic is as impactful to me as Costco selling alcohol and junk food. I don't play those games, so only reason I'm even aware of it is because of people bringing it up. Those who seek it out can get it those who come for other things can avoid it.
And I like the steam launcher when it comes to linux compatibility, steam workshop, reviews, categorizing my games, note function, and gamepad support. I absolutely would not want to go back to the old days of CDs for games. Too many to manage and keep track of. And I like my Steam Deck for introducing me to Linux gaming, and being one of the few launchers that actually has Linux support and doesn't need to rely on third party work arounds.
Those who don't value that can buy from Epic or other launchers the way some people don't see the difference buying from Costco vs Walmart and see membership fees as a waste of money. Or go over to consoles to be free of launchers entirely.
I'd say the only thing that bothers me about Steam is that you can't completely ignore updates for games, so have to go into offline mode or save a copy then update then replace the directory or use steam console to retrieve the old version if you accidentally updated. That's been my only gripe as a Steam user for games like Skyrim where I don't want updates.
