If you see developer rooting for using MIT/BSD licenses and especially replacing GPL with them, there is probably good 98% chance of them being corporate programmer that legal didn't allow to use GPL-licensed code and they are sad they can't steal everyone's work

Last elections for DPL it was the stated goal of one of the candidates to reduce the amount of copyleft in debian.

At least they didn't win.

A number of debian developers do that as part of their full time jobs for canonical, microsoft, and other companies.
