If I want to be a moderator, sure, some of those specifics matter because they're the "levers" I'll be operating (if they exist).

As a participant, one doesn't need to know any of that before choosing a new platform; the evidence for that is all the previous times one has participated on a platform without that knowledge (or without knowledge of how the specifics have changed over time). To a participant, the outcome is what matters, i.e. one's own participation does not feel constrained while also having the rest of the content seeming mostly devoid of spam and other undesirables.
