I'm not a big fan of companies advertising some place then going "LOL thanks for free advertising" and then taking off to another platform but still keeping their free advertising and free support. Wouldn't like it if someone did it on Origins, or GOG, or even on epic itself. Its a scumbag move.
Take Detroit Become Human, that I'm fine with, it promised exactly what it did, to be on Epic store...no problem there.
There is of course the morality of supporting Tencent who even if they don't own Epic, do have 2/5 seats on the board with 40% of shares+are really a china company, which means supporting the chinese government and therefor supporting the chinese concentration camps. And tencent/china are really one in the same. Even if tencent doesn't own epic, they still make money from epic so its still supporting concentration camps. Though in a bit in-direct manner.
(to add)
With that said, whether company has economic backing in...suspicious origins...
I never buy a game for 1-3 years anyway, cause I wait for 50-75% sales. And by then its developed and has a ton of expansions that are also on sale usually. I bought hearts of iron 4 after 3 years cause how cheap it was on sale, that and I like paradox games.
