Where do you set the personal boundry for evaluating an experiment as a failure or success?

E.g. in the case of social networks and what consequences Facebook brought us. When is the right time for Mark Zuckerberg to announce conclusive failure or success for his actions?

Pessimists say he should have admitted it years ago.

He himself doesn't even accept the premise of the argument. Rather he sees it as his personal calling or responsibility to build (source: see Lex Friedman podcast).

Who's right here?

Anyways, it isn't my intention to negatively associate digital or quadratic voting. Rather the post is an attempt at adding to a currently inconclusive picture through critique.

You could maybe try to argue that the implementation hadn't reached the minimum level yet, and therefore wasn't an MVP and it was too early to draw conclusions, but it sounds like you're just assuming that.
