Fair points, but I think the big thing is that very very few NIL orgs are going to disclose this information (HFG eventually being one of those exceptions), at least in the short term.
At the end of the day, it will be buyer[donor] beware, and if you are uncomfortable with the finances of the hysterics' org or just don't like them personally, then you don't need to donate. If the financial ambiguity is too much for a lot of people that want to donate, the hysterics will evolve to accommodate or alternative orgs will take their place. But NIL is so new, its going to take time to figure what the market for NIL donors wants/expects, and for the time being, its not going to be transparent, and may never really get there.
There's a lot to like about HFG, but if your primary interest is getting the highest percentage of your donation to athletes, or a specific sport in particular (most likely basketball) then HFG might not fit your goals
