“It’s probably Matt Mercer’s fault.”
Yes, but as I noted, interest in a game doesn't have to be unitary. Just because you like 95% of what The Deep Delver Game provides, doesn't mean you still can't find the same old "everything sees in the dark but the PCs" every bit as unattractive as you would in D&D. I have little evidence that people have a "take it or leave" it attitude toward any game system; if anything my experiences have taught me people are more likely to put up with it in big popular games because being able to find the common experience there is often a factor.
I do want to re-iterate that "no darkvision for PCs" does not automatically mean "everything sees in the dark but the PCs". In fact, I think taking that extreme devalues the narrative value of darkness. Sure, orcs and goblins and the like need light to see and they use torches and fires.
But then there's something hunting you that doesn't seem to need light....
