Here’s some more:

• Bought Rocket League and immediately stopped maintaining the perfectly working Linux version that people paid for
• Sold people Fortnite Save the World (PvE mode) and stopped caring about it when the Battle Royale mode took off, it was never finished

Also I don’t know if this is really anti-consumer but as an Unreal fan I still hate them for it:

• Stopped working on the new Unreal Tournament when Fortnite Battle Royale took off
• Took the old Unreal games off the store for no real reason
