You're actually the 1%. While everyone else is fine with their data and stuff being sold (i mean who isn't at this point), actively taking up proverbial arms against a free market tyrant because you think the profit split is unfair is...radical. I don't condone the data stuff, i don't condone shady practices, but i'm fine with having once centralized source of media. I'm fine with having a monopoly because it's a commodity. It's centralized, it's convenient. We're not charged extra for games, refunds still exist, and we're free to choose what we play and who we play it with.
Under no circumstances am i about to install 4/5 other launchers to play games when i can play virtually all of them through steam, both officially inhouse and through 3rd party plugins/applications that allow me to access that content through steam, and organize it within the library.
Also the profit split margin "make vs. break" ratio is negligible, in that, the potential profits of steam are higher in some cases than the epic/origin/discord fiasco on the fact that steam is widely known and is still viewed more than all other game media platforms combined. They're losing more money from exposure, or the lack thereof. And no one is forcing producers, publishers, or indie startups to put their products on steam, because they know about the split, they're aware and they're accepting of that. In their world, in order to break even from thousands of hours of development, in order to make a sale, you need one thing. Viewership.
Exposure is everything, marketing is everything. Publicity, views, capital. THAT matters. Putting a game on the epic store is the equivalent of starting your expensive law firm in the Alaskan wilderness.
I don't mean to bash epic, because i want to see them force steam to step out of their comfort bubble, but at the same time i'm a neat person and like all of my media organised in a concise and clear fashion. There can't be order when there are ten or more so media platforms that all take up space and all conveniently claim to do everything else the competitors do, but "better".
