I counter you with the Souls games, that are notoriously hard and unforgiving and don't coddle you in any form, yet people flog to them like moths to the light, so much so, they became their own genre. You don't have to dumb down games to be successful, just make them engaging. And it's not like DnD is a niche product anymore, everyone knows about DnD nowadays thanks to media, so that should bring in the customers. I understand the need for tweaking some rules to make it work better in a videogames, but there was nothing wrong with multiclassing according to RAW, you could still make very powerful characters and it is not hard. No need to dumb that down.
This is also why I brought up difficulty settings. Not every game has to be a Souls-like, but there are people who like a difficult experience. There are also people who enjoy just playing through for the story. There are going to be people who want to play through without the ability to respec... or when their character dies, they stay dead - it is why things like 'hardcore' mode got so popular in Diablo 2.
For all of the talk of choice the champions of choice sure do want to remove the choice from everyone else to have game modes or an experience tailored more toward difficulty and traditional 5e rulesets.
