So do you know everyone in the industry that made that such a claim? Sure, maybe you meant to restrict it further to "everyone I have noticed personally that said/wrote that" (or anything along the lines), but even then, do you know all the stuff that they did after saying it? (as the statement also included "doing the opposite" which I find quite strong).

If I see "everyone" I would expect it to actually mean "everyone under the constraints", the word "everyone" has a certain meaning and is very powerful, why use for situations where other words like "many", "most" might be more appropriate?
