I think a lot of people are using the " safety " as an excuse to not attend in person. I think more than a few have made a run for it over the last two years.
We have a family member doing this very thing. Refusing to attend in person meeting by claiming to be afraid of putting elderly JWs at risk because they work in healthcare. And yes, they have become another one of those MIA JWs who only remains "in" because of their zealous PIMI spouse.
