Gamers rage a lot, but they don't do much or stick to their guns often, so this strategy will be fine so long as Epic is working to address some issues. A few updates and patches, a few more games people simply must have, and nobody will remember why they raged.
I'm not thrilled with this, but I'm not going to stop playing Rocket League. I'm going to buy Borderlands 3 (and so are all my friends that grumbled about it being a time exclusive, and they'll buy it from Epic because we all want to play right out the gate together). I still remember people raging against Origin - most of them use it for the EA games they swore they'd never play again.
