ISC license is a simplified version of the BSD license due to the Berne
convention. It was also used for wireless drivers to help the BSD community in
particular OpenBSD who had picked that license for new contributions claimed
simplification of the BSD-2-Clause. Because of this reason many BSD communities
feel super comfortable with picking up kernel code in Linux under this license.

Granted, I'm on no longer a fan of promoting permissive licenses as it didn't
buy us cross-collaboration at all. We tried.

But it would be unfair to advice against a license unless a reason is stated in
favor of another BSD license. Why is the ISC license worse than the
BSD-2-Clause?
