It’s less money in their pockets and more money in ours. That’s not going to be a double win in their books.

Getting Epic’s money isn’t a slam dunk for profit. You’re hedging your bets taking guaranteed Epic money for lower potential sales vs non-guaranteed Steam money for higher potential sales. Having a bad exclusivity deal on Epic and then selling your game at a loss (90% discount) on steam isn’t profiting both ways, and sometimes isn’t profiting either way.

I also disagree with the sentiment that you’re reinforcing bad behavior. If anything, you’re signalling to them that you won’t support exclusivity deals, and are happy to wait for a deep discount on Steam. Ultimately, that’s a win for consumers.

That said, fuck exclusivity deals, and I’m much in the same boat where I’m hard pressed to support developers that take them.
