Is GPL-2.0-or-later compatible with MPL-2.0?
It depends — here's on what:
LGPL and MPL-2.0 can feed a GPL work; EPL cannot. See overrides. Result license is the more restrictive of the inputs. You must satisfy every input license's notice and source-offer terms. Verify pairwise compatibility first.
Resulting work's license: GPL-2.0-or-later
General guidance, not legal advice.
