Good call out. It's like the business equivalent of:
You changed the rules of the game because you didn't like how I played. So I'm not even going to bother playing with the new rules. I retire.
The rules of the game changed so severely that playing the game isn't just disagreeable, it's impossible.
What would you have done instead?
Charge $5 monthly and refund the annual fee for those who want it (which is already being done it seems, regardless of Apollo's future).
Apollo has options. They're just choosing to shutdown. That's the founder's prerogative, of course, but it is totally unnecessary.
Look at the support in this thread alone - Apollo has tons of people willing to throw money at them.
