This was not a crucial tactical error, it was a deliberate gamble. Disruptive communication is hard, and they lost this gamble. That does not make it an error

This was not a crucial tactical error, it was a deliberate gamble. Disruptive communication is hard, and they lost this gamble. That does not make it an error :) (Snapchat, Whatsapp, etc, all are things int he "must fully jump onboard or ignore it", and they've done fine, because they are incremental improvements that are less disruptive).
