If local congregations and individual JWs are willing to donate more than they did before the virus hit (or probably even just the same amount), then JWism will become an e-religion. I think the org is monitoring the situation closely to see what's going to happen to its income stream. If donations don't drop off, then it can sell off all Kingdom Halls and claim the scene of the world is changing, we're near the end, etc.
I bet JWs would be willing to donate more to keep the situation as it is now - not physically going to meetings, no door-to-door, etc.
