To what extent are you "entitled" to "investigate" into the personal lives of entrepreneurs and people building real value.

If your goal is not to intimidate, attack, or slander, what purpose does it serve and accomplish? Freedom of speech and self publication is important and is part of the Constitution. Entrepreneurs can investigate shady journalists who seem to have a bias and who are crossing ethical lines even if you think they shouldn't.

Looking into the financial ties of companies is game. But the industry and business is not the same as someone's personal life, their sexual preferences, children, family, etc.
