The rumored demands from Disney were kind of rediculous
50/50 cut of all profits
Wanted a cut of profits from Spidey related projects that weren't even MCU related
Disney still keeps all merchandise revenue
There's no reason for Sony to agree to that since it does nothing but hurt them.
Are you sure you got that right? Is there a link available?
Also with no risk to them.
They don't have to work for lesser profits, but neither does Sony have to give up valuable IP they paid for, either.
I would say that co-financing is assuming half of the risk.
