Transferring to an Eastern (or other Alternate) Rite was once a viable way to escape the disaster, but starting about in the 1990's or so, they too have had their gravely questionable "changes" of every sort, evident compromises (especially with schismatic East Orthodox, all at the direction of the Vatican leadership), and so forth.  As there are about a dozen Alternate Rites (I say "Alternate" because while most of them are "Eastern" there are some couple or few which are "Western" without being the Western Latin Rite), all taken together, and it is reasonable to suppose that the damage to some may be greater or lesser than the damage to others, or further along in being corrupted, or proceeding at a slower or faster pace, I cannot say for certain that all have passed beyond the pale, though by this time (20 years after the corruption of the Alternate Rites was begun in earnest), the chances of there being more than one or two which might still as of yet remain within the pale, however just barely, are practically nil.
There are a couple things to consider here, one being that all the Patriarchs and Major Archbishops of these Rites as were installed prior to Vatican II and (at least possibly) accepted or vetted by a real Catholic Pope are now all dead, the last few of that category having passed away in the mid-1990's.  I notice that it is the same general time frame in which they have begun to be most conspicuously compromised, for example with the Balamand agreement or suchlike.  And all such Patriarchs and Major Archbishops have been under the pressure of Vatican II to be influenced by its non-Catholic doctrines ever since the Council itself, and who is to say who among them might have yielded even while others may not have?
Which leads to the other consideration, namely that we Western Latin Rite Catholics (by birth or initial conversion) are hardly in a position to evaluate whether a particular Alternate Rite yet remains Catholic in content, belief, and profession (including liturgy).  We come there, after all, quite prepared to expect that many things will be quite different:  An Altar may be free standing so the celebrant can literally go all around it, or else it may be concealed by an iconostasis, or there might not be seats except a few for the infirm and nursing mothers, and that many of the prayers will be different, and who knows what all else might be different.  Would we Latins really be in a position to ascertain whether a particular Alternate Rite parish has been Novus Ordo-ized?  They might (for example) leave "for you and for many" intact (putting our "for you and for all" concerns to rest), all the while mutilating "the mystery of Faith," or the epiclesis, or something else, in some serious way that only those native and expert in such Rites (or at least the particular Rite in question) might even notice or realize the seriousness of.
