I think the author is confkating two different things. There are technical problems with sticking to constructive purity when it comes to mathematics (setoid hell, avoiding excluded middle, real number formalization etc). Then there are social aspects. The community's 'cultist' ( his words) adherence to constructive logic. Saying this is the reason rocq lost out to lean seems wrong.

Firstly, there is value of the attempt. By staying true to constructive logic, there was a lot of progress (compcert verified c compiler, cubical agda etc).

Secondly, there were other confounding variables (tooling, network effects). Claiming rocq lost out to lean due to community's obsession is a bit of reductive argument.

But author is an expert. I will defer to him. His point about sledgehammer approach working well in the new AI world is very interesting though.
