They basically got a bunch of people to look for bugs, then decided to screw those people over by making the game cheaper for people who did not actually help them out.
Games these days use early access players and such to hunt for bugs to improve games before release to save money/time on finding the bugs themselves, because the more bugs does not mean a worse game, it means less income as people don't recommend to others/reviews are lower.
Considering the saved game wipes and limited access to the game from early purchase really offers no benefit to people who actually help improve the game, so for people who fail to realise this, commenting "well sucks to be you" is about as helpful as a blind crossing guard.
And offering a sale on something before it is released means it's not on sale, it just means a bunch of people paid too much to help the game company out. I guess Larian studios don't like people being repeat customers.
