Barre isn't being "excluded" per se

He and Anderson split, permanently. There was an agreement that the Jethro Tull name died with this separation. Anderson is using semantics to re-animate the "band." He (and Barre) play Tull-heavy setlists anyway, and the anniversary being celebrated isn't 50 years of Jethro Tull, but 50 years since Jethro Tull (which doesn't exist any more) started.
It's a total joke - anybody who spends money supporting this nonsense should be shot. Anderson is one of the greediest, narcissistic douchebags to ever play rock music.
