Just to be clear: one can't escape the Pope and stay a good Catholic on the path to salvation by becoming a Schismatic (Orthodox).
So you might as well "escape" to Protestantism or Islam. You avoid the Pope question -- and eternal salvation -- there as well.
Eastern Rite Catholics are still under the Pope, just as much as Roman Rite or any other Rite in the Catholic Church.
A good clarification above, and I agree. One cannot really avoid the Pope question just because one goes over to the EO. They will still have to held accountable when they face judgment. I was just pointing out that it has occasionally happened that a sedevacantist, tiring of dealing with the issue of a heretical pope, goes over to the EO. It shows that one can burnout when focusing too much on the pope question.
Ultimately, the bottom line is that as Bp. Williamson and others have pointed out...."when the shepherd is struck, the sheep are scattered." And yet God has allowed the Crisis by His Permissive Will. And that is why, IMO, it's not prudent to take an extreme position.
