It's because epic store launched with "exclusive access" being a "perk" to attract users. I fucking hate that shit in the TV/Movie space so I decided to not support it.

Also, using that as an opening move suggested that they'd enshitify as soon as they have the market power to do so.

Plus their anti-linux stance. Not just not supporting the shift to linux but specifically against it by removing support that was previously there. And they killed off the UT franchise to be sure it wouldn't compete with Fortnite.

Even the reduced commission rate just seems like a play to build market share to be abused.

Meanwhile, the biggest negative I've seen from valve is cosmetic lootboxes that you can ignore by not playing their games or not buying lootboxes if you do.

It supporting Gaben into billionairehood isn't great but he's one of the few that makes things better by still being around (because who knows if the next one(s) in control will sell out or not). Plus, with him already being a billionaire, MS can't change his course by throwing money at him.
