Wavelength
IMHO the core point is John Gruber equity, so it is basically a business promotion not an article: "Not only was my feedback warmly received, it begat a series of discussions that culminated in my gladly accepting a position as an official adviser to the company, in exchange for a small amount of equity. I’m happy to disclose this now, and will continue to disclose it when writing about Wavelength henceforth.".The disclosure was made almost exactly in the middle of a long article. Not at the beginning.Excuse me but gentlemen don't do that.
