It doesn't matter to GTO long term. If opponents aren't value betting thin enough on the river and you are losing money there by calling too often, then you are making it up elsewhere in the overall strategy. Importantly, GTO is not a profit maximizing strategy, it's an unexploitable strategy. It will never do worse than break even if you do it perfectly (which no human can), but it won't always make you the most money. And the bankroll needed to execute it perfectly given where you might lose value in some hands is probably larger than most players generally have.I agree that studying GTO has a lot of educational value. I just think that in application, it has weaknesses along the lines of, say, Google Maps.
It's excellent for giving you a generally optimal route from point A to point B, in theory. But you need to have the sense to deviate—sometimes sharply—when it's obvious that the suggested route won't work (e.g., tree in the road, players who never bluff the river). And those points of deviation are all over the place in poker because you're constantly getting information about your opponents.
The funny thing about the example we were discussing is that it's about an anonymized player pool, not individual known players. This is the type of spot where GTO should really shine, since you have no exploitable information, but alas, it does not. River spots should be among the simplest to consider for a GTO approach, and yet that's where it's failing the most clearly. I have to wonder if the approach the software is suggesting is not truly GTO.
It's easy to brush this off as "Players on this site almost never bluff the river, so this doesn't really work here," but that shouldn't matter for a GTO approach. GTO may leave some money on the table compared to an exploitative approach, but it shouldn't have you getting constantly value-owned on the river.
Learning it is a good base, but against people that aren't going to counter you or have obvious flaws (player pools in micro stakes fast fold), you are free to adjust to increase profitability. But as I said, using it for the more common spots like preflop ranges, cbeting frequencies, board textures, and optimal bluffing hands, it has a lot of value.
