Now as a pure GOG game buyer, used to having to wait decades to get games that were released on Steam on release day, I can't say I'm not finding some satisfaction out of all the Epic exclusivity outrage but, feelings aside, I'd prefer that there was no exclusivity whatsoever.
If the developer gets more money from Epic, that means that they now have more resources to make a decent game, which actually benefits me as a consumer.
Also, if the game is good, I'd prefer more money to make its way to the developer rather than storefront and Epic has a better deal.
From all above it seems to me that Epic Store is overall doing a good thing and I'd prefer it to Steam if I had a choice.
Because other people are not you and have different things they want. I know that must be difficult to accept, but it is true.
That's not such a big deal though, the real problem is that they did this with games that were in development for years with Kickstarter-style backing that had up until that point explicitly targeted other storefronts. To many this seems like a betrayal by the developer and Epic's behavior is making the market worse.
