One way a company can protect an open-source product from large cloud providers is to restrict the license to forbid some commercial uses, typically offering the software as a service.

The community and programmers in general almost always dislike these moves.

One thing I have seen little discussion of is clauses like: "after N years, this license becomes MIT/GPL."

To me, this seems to solve most of the practical issues, while obviously doing little to address software-freedom or boiling-frog concerns.

Do you agree? Would such a clause change your opinion?
