open source license with 24 month proprietary clause

[Jeremy C. Reed]

Has anyone heard of an open source license where new code based on it can
be kept proprietary for 24 months?

Then after the 24 months that code becomes part of the public code base.

I read a magazine article saying that the BSD license does this 24 month
innovations claim.

Time for a letter to the editor ...
