Given that the original comment implied that the reason we could not have an "open and really big" internet is because of the handful of oddballs that thought 5G towers caused Corona, yes, it might as well be literally nobody.
The number shouldn't matter though. We can have an open and big internet regardless of how many people believe in ideas that seem to be batshit crazy to the average person. Who cares what someone else chooses to think or believe?
you can still have an open and really big internet with these people, the question is if it remains anything like the bastion of great thought the "open and really big" part implies (along with the example provided in the original post I was replying to)
