If you dislike Honda as a company (for subscription key fobs, or crappy warranty practices, say), you can still like the cars without giving the company a single dollar, by buying used cars. I suppose this doesn't quite work, because EG is still getting money for UE.

Perhaps an inversion: Amazon Basics are usually trash, and many consider giving Amazon money distasteful, yet the storefront is definitely quite effective and the shipping fast. Denigrating one while using the other is common.

As for the different treatment, the people behind UE seem to make decent decisions (especially in the light of Unity's recent decisions), while the people behind EGS have done nothing but aweful anti-consumer crap. They're both owned by the same company, but behave differently, so different treatment seems reasonable.

That being said, there's lots of people in gaming communities who whinge just to whinge. No changing that. I don't get much of the hate for Steam, but I do agree that having a monopoly is bad, no matter how benevolent Valve is right now. EGS should have been the silver bullet to that situation, but the silver was arsenic, the bullet was hollow point, and they tried to shoot us instead of Steam.

When Epic stops trying to kill user fteedoms and divide the market, and instead make a competitive service, they'll get far less hate. They'll still get hate, that's gamers, but winning by damaging the market is always bad.
