I have forked an open source project after the original maintainer has not responded for almost a year. The original developer left things in a bit of a mess however, and while there is a LICENCE file with BSD-3 inside, there's an MIT licence in comments at the top of 2 files in the repository.
I'm planning on refactoring, and perhaps removing, these 2 files, but I'm not sure what happens to the licences within?
Should I just put both licences in the LICENCE file, or are they similar enough that I can put one or the other?
If putting one licence in, it seems BSD-3 is more restrictive, and hence that would need to be the one I put in the licence file, but the MIT licence explicitly says not to remove it. (Does that apply if I remove/refactor the files it is in?)
