> Isn't bundling GPL jar and proprietary binaries a GPL breach?

<del>maybe? IANAL, but it's at least a bit fishy IMO.</del> I think it might be fine actually, but I'd need to check more into what code comes from where and who holds the copyright and such. In general, taking GPL code and building something proprietary based on it is a breach, but I don't think that's happening here. I think they are dual-licensing some parts under both their proprietary license and under the GPL, but keeping some core things to themselves which are only released under the proprietary license. If they are indeed shipping GPL code for which they have no copyright in binaries for which they don't release the full source code under the GPL, then that would be a breach, yes.

Still, I don't see any harm in shipping this as a package in non-free, right? It's being shipped by a few other distros as well, see https://repology.org/project/makemkv/versions
