In reality, it seems like what WotC really cares about is the number of people subscribed to D&D Beyond.
That's probably true, given that they hired Dan Rawson to run D&D, and his primary area of expertise and experience is converting people to digital subscriptions.
I very much doubt they're modifying 5E to resemble BG3, but only because the management layer seems to largely disconnected from specific decisions re: mechanics. They seem to be strongly connected re: tone and general approach, and it's possible they're reconsidering those, because they're absolutely at odds with BG3 (which is essentially R-rated, where WotC has been pushing D&D pretty hard towards PG, not even PG-13), but I don't really see how that would be reflected in the mechanics of a playtest.
Now, if WotC's management were a bit more on the ball, and a bit more forward-thinking, they would be looking at BG3 and thinking "Do people find this approach to mechanics, which is more permissive (and frankly has a better martial/caster balance than 5E - very much including 2024 - does), to be more attractive and fun?". And I suspect the answer for the vast majority of people who play D&D would be "Absolutely, yes, it is preferred". However, I suspect the answer for the 20K to 40K mostly-grogs who answer the survey is "No", because they're generally opposed to change, and particularly to martial classes being improved meaningfully (one of the reasons the weapon actions got a positive result was that most of them seem fairly weak, and it's clear from discussions here and elsewhere that a lot of posters just didn't grok how OP a couple of them are).
