Regarding the original post, it depends. I like Antiochian WRO. Met one of their priests. They're not Catholic but not anti-Catholic either; quite the opposite, just like '50s high Episcopal.
ROCOR's anti-Catholic so I found their Western Rite operations offensive but mostly harmless.
95% of American Roman Catholics have little if any knowledge of the existence of eastern Catholicism. Probably 99.99% of them never heard of WRO.
Most Orthodox are at least aware of Eastern Catholicism, but I suspect 95% have little if any knowledge of the existence of WRO.
ROCOR's WRO had no more than 500 - 750 members total. That's one small RCC parish.

That's fine. As I've been saying, the Catholic goal is corporate reunion. Never-Catholic Orthodox get the benefit of the doubt. So individual conversions aren't solicited
but, because of the true-church claim, they are accepted
, now quietly.
I don't like the Ukrainian Catholic Church's moving their HQ to Kiev either. Goes against what I wrote above. But it's understandable considering how the Russian Orthodox treated them under Soviet rule, and if you're afraid of competition from them, maybe you're vulnerable over there. And... are Soviet-raised, never-churched Russians/Ukrainians fair game, unlike born Orthodox? Fair question. I'd say, be nice and work toward corporate reunion, so let the Orthodox in their native lands have first crack at them.
