I don't see how it makes an iota of difference from the consumer standpoint. If anything moneyhatting the release for timed exclusivity gives more control to the developer you may get it on your storefront of choice in the future if you don't want EGS cooties.
They are both inconveniences to the consumer that benefit the devs.
in the case of a straight-up money hat, the game would still have been made and came out on more preferred platforms (or in the most egregious cases, was already announced for other platforms)
in this case, the games have a greater chance of not existing (if the dev was unable to find a different publisher). By assuming greater responsibility for the game, Epic earns greater leeway in where the game is sold.
That's how I see it, at least. Funding the game from Day 1 means that it being exclusive to a single storefront is no different from Ubi or EA restricting games to their stores. Annoying, but justifiable.
Straight-up moneyhat doesn't carry the same justification, imhho. Although it's obviously considered a safer bet by a dev or publisher in charge of the IP.
