I agree with your complaint. The whole point of multithreading is so
that the app will appear to be very responsive to user input. Things
that don't show to the user get put in background threads.

This is totally unacceptable for any program that reads stuff over a 
network. It must update its local database in a transactional, 
restartable manner, so that it transparently recovers from random 
network outages.
