Bambiraptor got a reaction from Blackbird in Shenmue III developers refuse Kickstarter refunds for Steam keys, they state Epic Games Store is the "best distribution platform option"
And therein lies the crux of the problem. people who "don't like it" as you put it got bait and switched into an EGS release effectively taking the choice they were promised out of their hands. No wonder they are pissed, i would be. ¯\_(ツ)_/¯
