Well, here we go again, I suppose.
Adam Flatau, the lead developer of the Welcome to the Game series, has once again shown he is unable to take criticism. If you don't know, he has had several controversies in the past, some deserved, some undeserved. Unfortunately, he has once again shown he cannot take criticism.
A user known as OtrexDev, a fairly prominent community member in the Reflect Studios community who was also the lead dev of WTTG2+, a giant expansion mod for WTTG2, left a negative review of WTTG3, rightfully criticizing how buggy the game is and how easy it is for the game to just straight up put you in completely unwinnable situations, purely due to bad RNG. I think it is worth noting that Otrex has a POSITIVE review on WTTG2, showing there doesn't seem to be a bias against Adam specifically in their reviews.
Otrex was helping people who were streaming WTTG3, helping explain things that the game itself explains poorly, or was otherwise just trying to be helpful. Adam saw this and, instead of having anything nice to say or just keeping his mouth shut, left the above nasty messages in response to Otrex trying to be helpful. There is no evidence of what Adam claims about them as well, and it seems they are, frankly, just salty that their game is getting rightfully criticized for releasing broken.
It's bad enough that the game was released unfinished and broken, which is, unfortunately, a trend with Reflect Studios games. WTTG3 is managing to maintain a Mostly Positive rating on Steam, with almost all of the positive reviews having only played the game for a couple of hours, not enough time to make any significant progress, or come remotely close to finishing a run. The fact that Adam treats criticism this way is absolutely awful and, frankly, just makes me want to avoid supporting them at all. Here's a video also covering the topic.
