I think there would be something along the lines of would be what's required:
"Disclaimer: [$thisBlog] is an investor in [$company]"
...right underneath the story headline involving a company they were involved with. It would force "journalists" to at least pretend to be somewhat objective.
Yes I think that is a minimum. Still the other concern is the kind of racket that is described: you pay or we won't mention you, or worse we will destroy your reputation (hitman).
"Or, don’t buy a subscription and I will bash you relentlessly.” Most big companies paid up and considered it a cost of doing business."
