Eric's last sentence in the fRoots article is extraordinarily generous and restrained.
Having now listened to the Joss Stone version (previously having wondered what was so awful that yet another petition had to be started - yes I also suffer "petition fatigue") - it's a massacre of the original song. I've never been comfortable with the Furey's version: only Eric's and a very few other people's singing of it "do it" for me.
It's one of those songs that so often get murdered in sessions, and have you thinking "oh no not that again" - unless it is done really well, in which case, yes, the tissues come out. If Joss Stone felt so strongly about doing an anti-war song, let her write her own and not tamer with such a well-written, well constructed, heart-felt song as Eric's.
