Thank you. You get it: the whole system is just broken.
Trying to shift that 15% away from Valve is effectively putting it into the pockets of publishers, as the overwhelming majority of video game sales are either developed by large publishers like Activision, or stuck with a third-party publisher that isn’t just going to voluntarily pass the savings on to the consumers or developers.
If I buy a game on Steam, I know that 30% of my money is going to end up in someone other than the developer’s hands. Support the devs by buying the game directly from them or on a lower-fee platform like Itch* wherever possible. Or, if it’s only available on Steam and my money it going to go into some corporation’s pockets, Valve is at least not legally incentivized to milk its consumers for the sake of shareholders.
*But never Epic. For as much as they preach about monopolies, their hypocritical actions demonstrate a clear desire to become one.
While I disagree with the other commenter’s approach and attitude, he/she/they are partially correct with the comment they left next to this one.
There is no legal obligation for a company to fund or assist its competition, even if it holds a significant marketshare. The companies that do help their competition, like Microsoft with Apple in 1997 or Google with Mozilla today, begrugingly choose to do it so their lawyers can make the argument that they are not a monopoly because they still have competition.
