There's nothing illegitimate about raising money without selling voting rights. You want voting rights, want to play active investor? Buy another stock.
Sure, you can do that too. The comment you're replying to is arguing that all these options are legitimate, and buyers are adults who can buy something that matches their investment theses.
There are all sorts of rules you have to comply with to be listed on a public exchange. One of them used to be equal voting rights. I am fine with buyer beware, but it is really important to understand that "buyer beware" is not the philosophy that the NYSE / NASDAQ was built on.
