I didn't eat meat this year. I'm not a Sedevacantist, but I wasn't sure if the indult was real, and even if it is, I didn't know if it applied to Byzantine Catholics (I'm Ukrainian Rite.) Not eating meat on any fridays of the year actually is still binding on us too, unlike the Latin Rite.
I did not ask the eparchy myself, but I did talk with the cantor (and de facto parish leader), and he was not familiar with it from the eparchy.
Refugees from the roman rite attending an eastern parish are bound by the roman rite rules, of course, unless they change rites, which is a process.
