The FIA didnt apologise for any fault on their part, Ferrari 'supposedly' didnt receive the email on time, now if all the other teams received this email in time, it was either Ferraris fault with their email or Ferrari ignoring the info sent to them. As a result of this the FIA decided to remove any possible doubt in the future by hand delivering this type of info - end of.
Hand delivering the notes will cause all sorts of other troubles. They are going to need 11 (next year 12) runners who can deliver the note the right person at exactly the same time so that no team can claim that they were disadvantaged by receiving critial information after others and so having less time to prepare.
The electronic system currently in use has been in place for several years (and working well) and is used to avoid situations that can occur when trying to manually deliver information. Ferrari probably were trying a fast one, which backfired on them.
