Asserting that using centralized services would be immoral is sloganesque and hence thought provoking.
However, the generalization wouldn't convince any rational agent because the use of some centralized systems is beneficial (think air traffic rules).
Therefore I would reformulate the slogan as follows:
USING CENTRALIZED SERVICES WHEN DECENTRALIZED ALTERNATIVES ARE AVAILABLE IS IRRESPONSIBLE.
#Decentralization #system
