MIT is permissive. It can be relicensed into GPL fairly easily, much
like LibreOffice took the similar Apache licensed OpenOffice into the
CopyLeft. It made for a one way gate, new code added to OpenOffice
could still freely move to LibreOffice while innovation occurring on
the LibreOffice tree could not go back to OpenOffice. OpenOffice is
now pretty much a moribund project.

It isn't the friendliest move, but it can be done. I'd suggest Mr.
Chung study the license files in the LibreOffice package. But first
try for a peaceful arrangement with the original author; just because
something is legal doesn't mean it is the recommended action. If there
is ever to be a hope of cooperating with the original author both
efforts need to be using a license you can both live with.
