I think STFU is brilliant advice and I do it myself. A metaphor:
In 1866 a young shepherd named Erasmus Jacobs found a small white stone on the bank of the Orange River in South Africa. It turned out to be a 21 carat diamond which they named "Eureka" and it kicked off a diamond rush in the area that centered around Colesberg Kopje. Turns out that this little hill was an old volcanic pipe filled with diamonds and every prospector for thousands of miles descended on the place and started digging.
Here's what it looked like:

Every prospector had their own pulley and own demarcated area they were allowed to dig.
So if you were digging in, what is today called Kimberly's big hole, and started finding way more diamonds than anyone else, what would you do? Start giving everyone around you advice about how and where they should dig?
Sadly, business is largely a zero-sum game because customers and their money that we compete for are finite.
