Technically DBZA and Hellsing Abridged don't earn them any money. They spend time/effort on them and get zero money in return.
What they do get is popularity, and they can turn that popularity into indirect money by making things like other videos (ones which are allowed to earn money), selling merchandise, and they get like $10,000 a month from Patreon. Those revenue streams will dry up if TFS doesn't stay relevant by doing popular stuff like DBZA. If DBZA ends and TFS can't find a suitable replacement for it's popularity, they're probably going to have to quit being TFS.
I assume that being in TFS is a well-paying gig, even though they're obviously doing it partly out of love (that being the whole reason why they started). I haven't seen any indications that they're burning themselves out and the only thing holding them together is their drive to complete DBZA. So if DBZA is completed, I think they'll try to find a new reason to stick together. It shouldn't be that hard for them to find something new that they love, which is also popular.
Just go back to DB or move on to super. They have enough materials to do this till retirement age.
