2) Unknown holding company: yes, people can have general knowledge and to a degree it's their own fault for not knowing. But it also isn't, nobody has time to read about what thousands of brands are out there.

Absolutely. I remember going to Ed's Diner here in the UK. They made a great burger in SoHo before I left the country for a few years. When I came back, they'd expanded across the country, which was a bit surprising to me, but I went in to eat there because of my previous experience. I took one bite, it was terrible, and I immediately told my wife "this tastes like private equity". I go on google, guess what, it was indeed bought by PE and they'd totally changed the burger. This is a form of lying to people that should not be tolerated but of course is a grey zone because it not easy to define when you've changed the burger so much that you can't call it the same thing.
