So they're reporting earnings tomorrow, and they chose to release this news update today. Is it to signal that their initial 'test' of these fees was a success, and now they're rolling it out more broadly? Or is it because they have lousy results to announce, and they want analysts to see that they'll be improving their margins (among people who don't bail, that is) with these new fees?
