Alright, but why is it not possible to satisfy both licenses?
If I incorporated some code under my license (A) into some BSD code
(B), then A is governed by my license and B remains governed by the
BSD license, correct?
Can't you just provide the source code taken/modified from my
license along with the BSD/MIT distribution to satisfy both licenses?

True, they are philosophically incompatible. However, in practice, I
think they would play quite nicely together:
By incorporating code under my license, an MIT or BSD developer is
not surrendering his entire project to my license -- he just has to
do some extra work for the portions of his project that are based
from my code. That "extra work" is simply to make the source code
(only for the portions under my license) available upon distribution.
Since most OSS projects make source code available anyways, they
would not have any problem incorporating code under my license --
unless, of course, they strongly believe in their license's philosophy.
