The sheer confidence in the move was shown at the announcement (read, lack thereof).
As per usual, Epic's store isn't remotely close to being trustworthy, secure, feature rich. It remains with poor support, hilarious flimsy policies, curation and development path. As a customer, the decision is easy not to purchase from such a vendor vs everything else.
So in this case, I'm perfectly happy to continue not purchasing. The real problem is that with every mis-step from Epic is yet more lack of trust, uncertainty and doubt in the service. I don't expect to use the service till it is demonstrably supportive and competing for me as a customer. Locking down games, isn't going to change that, just as single games or even a handful doesn't sway me to any one platform.
In place of Borderlands 3, is Rage 2 of all things!
Though with Valve Index around the corner with Knuckles, that is looking like a strong contender for a bunch of my money and gaming time.
