It’s simpler than that: they don’t trust the people they choose to work with. So they are making bad decisions (based on mistrust) from the outset. Companies and orgs like that don’t do well in my experience, and don’t tend to grow, get larger, etc.
We also trust users (at tl2 and tl3) to do things that are “illegal” in 99.9% of other forum software. Our model is to add trust, not remove it.
