It'll be interesting to see. My gut feel is that stuff like the dreaded youtube algorithm might help us a little here.
Ten years in the past, this would have been a storm in a teacup. If you weren't actively on ENWorld or similar, you'd probably have never heard about any of this (unless post facto you saw stuff disappearing from the shelves of your FLGS and asked the guy behind the counter why).
Now, we have the algorithms. Even a casual D&D player has probably at some point watched an episode or two of Critical Role, or checked out WotCs Dragonlance trailer, or whatever. The algorithm remembers, and once you've done that, it'll feed you related videos forever. Right now, pretty much every bit of D&D content going up on youtube (and probably tictok etc too, but I'm not on there so i don't know!) is all about this OGL stuff, and that's going to affect recommendations. It's going to bring the issue to the attention of a whole lot of more casual players who probably have never heard of ENworld or even the OGL at all. Whether or not they actually watch the videos or care is another matter, but it'll be harder for people to be completely oblivious to it.
And as I've said before, Critical Role have enormous power here, should they choose to use it. They have nearly 2 million subscribers on Youtube alone, and then there's Twitch etc. I wouldn't expect them to criticise WotC publicly over this while OGL 1.1 still hasn't been officially released, but if they did eventually speak out, they'd bring the issue to the attention of a vast number of people, and that'd be a PR nuke that even WotC would find hard to withstand.
