There is also the good point (credit Febo) that no one has the right to tell anyone else what to say or not say. The suggestion of "retiring" the advice is out of line on that basis.
Sorry but that makes no sense. Everyone has the right to tell anyone else whatever they want.
The suggestion of "retiring" a strategy isn't out of line at all.
It isn't out of line to
suggest it, sure. But expecting to 'retire' anything is illogical. There will very likely always be someone who continues to give that advice. It'll never actually be 'retired'.
Furthermore, when and how did it become a "strategy"?
