It is a commonly used phrase in the BTC community.

BTC has proved to be the best. There have been loud critics that convert from critic to advocate as they progress through their understanding of BTC. It will never be as cheap as when they were a critic. So they pay a higher price for SATs when they become an advocate. Turning the corner from critic to advocate usually comes with studying and understanding what makes it special. So until a person puts on the time to study it the more expensive SATs will be when eventually turn that corner. Hence everybody gets BTC at the price they deserve.

I hope this helps.
