From the old days
For many years, Cato the Elder used to end each of his speeches to the Roman Senate (whatever the subject matter) with the comment "Carthage must be destroyed". Eventually, after much prevarication, the Senate and People of Rome took the hint and launched the Third Punic War which resulted in the destruction of Carthage and the establishment of Rome as the pre-eminent power in the Med.
In this context, replace 'Senate' with 'GNU/Linux camp', 'Carthage' with 'Exchange', etc., etc.
(NB Don't whine that there are already viable alternatives to Exchange because all those punters running Exchange still clearly don't regard them as effective and attractive substitutes).
