The middleman fees you talk about are meant for people to be able to convert HBD into whatever they use to purchase subscriptions, rather than opening up a leeway of me doing it through gift subs where most transparency goes away. Instead they'll get hbd onchain.
I haven't decided on the fee I'll take yet since this is experimental and unsure the time commitment it'll take to keep tabs on all the applicant's repo's etc, I'm guessing 10-15% as I mentioned in another comment on the previous post about this, max 20% if it becomes a lot, if it becomes more work than expected I'll probably discontinue the experiment or if there's very little results from it.
