I feel like to an extent that is the usual response to any sort of attempt at disruption.
For example, prior to Falcon 9 the argument used to be that SpaceX too would have to either succumb to relying on expensive cost-plus contracts or go bust like all other space companies before them. Yet, as they pushed up against that attitude and tried their own approach, they became successful and set the model that has now led to hundreds of new private space companies. Similarly, the argument against reusing F9 was that it wouldn't fly often enough to pay for reuse.
Thus I think that it isn't too crazy to consider that maybe with all this fiddling around they might stumble upon a more healthy model for social media for their scale. Especially considering that this environment of a large platform with an existing userbase undergoing said change is very unique (in that most other attempts at healthier social media have failed in part due to not being able to rely on pre-existing network effects).
Maybe they'll still fail, but I think it's still worth trying (even if it kills Twitter) rather than just appointing another 'expert' to continue to make things worse. Especially because it isn't my own money on the line :)
