1) Teams making it to the playoff final will lose money due to the reduced tv revenue
2) Teams finishing 5th will make more money (unless the tv cut is more than, say, 30% and compensates for the 2 weeks salary cut, which would be a distaster)
3) While now finishing 3th or 4th is always economically preferable than finishing 5th, in the future that might not be true for everyone.
with this calculations, 4/4 isn't economical wise then finishing 6 - don't know if that is betterwhen you tank for place 6 instead of 5?
But i can tell there is an difference in visitor income, through past seasons. Laim making incredible more visitor income then the rest of league, and my visiotr income raised also after an succesful last season and was quite better then the one of the 5 or 6th placed team(there was a standig bug so i don't know, on which placed he finished for the survey) which also have a good season and a better cup run. We compared it this season from time to time, and for laim we wondered since seasons, and copy his entry prices didn't worke you still have earned nearly 100k less^^(mostly you lost money through it)
So there is a benefit to play succesful, even when you maybe get a short term bonus in beeing a bit less succesful.
But a thing which is solved, is imho the risk of an economical disaster of a bad loss in the offseason when you had then an expensive rooster without income anymore. The last season, i always tried to get 1-2 Mio before the Po starts, and still ended in the red numbers and for players who run a more risky strategy this could be a reason to quit.
