From their perspective, they're retaliating with the same force MG is supposedly using against them. I could understand that, if MG was actually behind the harassment, which this lawsuit would be the best place possible to lay out their proof for but ended up not being convincing enough not to cost them 70k pounds.
I doubt they'll be convinced that MG isn't behind the attacks, but hopefully their weird lashing out against him will stop now.
I hope TR/TM do find and stop the harassment they receive, because as much as their libel is a problem, they actually are victims themselves.
