Nothing, and that is exactly my point. I have nothing against monetization at all.

What I am saying is, that if the elevator pitch for the project you are trying to monetize is "this is a replacement for $MIT-LICENSED-PROJECT" you will have a hard time.

The question the elevator pitch should answer first is how much this brings to the table to make me consider paying instead of just using the permissively licensed project for free.

But it is a replacement. One project don't need to be a pareto obtimum to claim to be replacement, it's ok even if there are some drawbacks.

Having to pay is clearly one drawback for some, but if you save this money by not having to develop some features or getting some support, then it may be worth it.
