Did you guys even watch the video?
Most of what he's complaining about is the fucking restrictive mission design. I tried to flank in one of the missions myself and got a failure screen cause I got too far away from the gang. It's the best open world with the least open mission design. Just follow the text on the bottom of the screen.
This has been an issue since gta3 tbh.
RDR2 is my GOTY by a long shot, but it's hard to argue that the mission design can get comical in how it wants you to just follow the on screen instructions to look at all the little things they have "prepared" for you, which is kind of antithetical with the idea of open world.
But then again, everybody else isn't doing that much with mission designs in open worlds either, even something like Breath of the Wild, reserves most of its freedom for the more roaming stuff, and had to curb its dungeons significantly, too.
I guess more obscure WRPGs can provide some examples of freedom in that sense, but even then, we're talking about a very different market, that R* is catering to, a market not primed for that level of jank (not from a R* game).
They could (and should) relax a bit, but i doubt they'll ever feel the need to, given their constant streak of commercial and critical success.
The only upside here, is that they managed to really control the pace of RDR2 incredibly well, for an open world with a ton of shit to do, and same goes for the tone, and part of that, is because they limited the shit you could do in critical missions, to just following the yellow dot and executing the command as instructed.
