Of course I completely disagree with the OP's claim. I'm an old-school hardcore roleplaying-centered cRPG fan, a D&D fan since the early-90s, and a passionate fan of both the BG video game franchise and the Forgotten Realms setting having read almost every single novel written in that setting. And I very firmly don't see Larian as having made this game for me, and sometimes even wonder if Larian is intentionally looking to stick their finger in my eye. So no, claiming this game has been made for everyone is clearly disingenuous.
People throw around the word disingenuous so often. It doesn’t mean incorrect. You are accusing the OP of lying; saying something that they know to be untrue.
In the initial thread that this one is responding to, that OP was gatekeeping the game; trying to draw distinctions between legitimate fans and new “casuals” whom they saw as ruining the game for legitimate fans by Larian catering to them. That thread’s title was “who is this game for?”
This thread is rejecting the notion that the game should be subject to gatekeeping by saying anybody who wants to play it is welcome to do so, and Larian trying to reach new audiences is a good thing. It’s not saying everybody needs to like the game and that it is actually designed to appeal to everybody in the world.
