Here's a different take, as a game dev:

Epic actual employs quite a few people who work with Linux. The Unreal engine (and even, to a certain degree, editor) has native support for Linux.

The reasons they're not including Linux support in their store front are two fold:

1. There aren't enough pure Linux users to matter, and whatever percentage of their userbase would use Linux isn't going to be large enough to make a dent^[1]^.

2. The only serious Linux user base in gaming relates to the Steam Deck, a product that pushes a rival (and the dominant) store front.

While Valve's move to push Linux gaming is brilliant for us gamers, it also kind of cements us in their camp.

There is absolutely no reason for Epic to support Linux in anyway, and it absolutely supports their bottom line to attack it.

And, no, it isn't because of any David v. Goliath tale of a little guy standing up to a brute: it's because a fellow giant has decided to ally itself with Linux, and all of us have - invariably - been shuffled into their camp.

I think the Epic Games Store has a place in this world as a niche storefront with limited visibility but higher access to sales profits as a result of that.

They'll never grow to the size of Steam, and that's okay. The largest storefront in the world supports Linux not just on its platform, but by developing tools for everyone that makes Linux gaming viable. That is enough, IMO.
