They did the same thing here in South Florida (Ft Lauderdale area) when they sold our assembly hall to a spanish evangelical church. It was really a beautiful building that I did some work on 25 or so years ago.
It was right next to the everglades and even had a pond in front of it (they had to fence in the pond at one point to keep the alligators out ... lol). If was full of fish and the water was crystal clear.
So I guess the building that was once dedicated to Jehovah was then disfellowshipped for apostasy and we are to shun the building now.
