This is very sad news. Mgr Abrass is a fine scholar, though I know nothing of his reputation as a bishop.
One of the chief starting-points for the momentum behind the Zoghby Initiative was when Rome went over the heads of the Melkite Catholic Synod in order to force the retirement of Met Grégoire Haddad of Beirut in 1974. This led to a joint meeting with the synod of the Orthodox Patriarchate of Antioch, as a show of solidarity, and did a lot to strengthen the ties between the two churches.
While it may be, from what's been said above, that this is a rather more clear-cut scenario of a bishop needing to be removed, I think it's safe to say that the Melkite Church isn't nearly as interested in defending its independence and prerogatives as it was in decades past. It's very noteworthy that Rome didn't just remove a bishop, it also chose the temporary administrator for the diocese.
