Apple was giving away the Keys to the Kingdom by way of licensing Macintosh clones, among other things. If ATG were responsible for hemorrhaging cash I am not sure why they did not re-appear then when Apple was firing on all cylinders. Only Jony was crowned.

And there's no way the library and its books were a cost — unless perhaps it was attracting snooty engineers who were reading Foley and van Dam when they should have been fixing bugs. ;-) (That actually might have been me.)
