Biggest evidence of that is Epic will give away games for free, but there will be people who prefer to pay for the Steam version over the free version.
Ehhh as much as I’d like to think that’s true, I think that has more to do with managing a bunch of clients and launchers. And also that those clients and launchers are full of spyware and bloatware and ads.
I used to not buy anything on Epic but then I got Heroic Launcher and now I’m not so terribly opposed to it. I have the Steam launcher and then I have HGL for Epic, GOG, and Amazon.
