Time and again we see this top-down police push that don't consult key stake holders (farmers, merchants, consumers etc.,) or fail to consider their feedback ending in a disaster.
To top it off they rolled it out 100% (No A/B experiment, so to speak). These big changes have higher order effects that manifest post launch and can't easily be predicted. They denied themselves a chance to adopt to those higher order effects by launching it overnight. The result is not too surprising.
