> the question is then why in the world they should care about this persons opinion?

Oh yeah, that's totally different. All we know if that this commenter finds the practice unethical and that's it. There's pretty much nothing one can do with this information without some further backing.

> he's slandering innocent people

That's a bit strong, they are just saying that it seems unethical. They find that maybe it's unethical. It's not less nuanced than that. Ethics is all about opinion anyway. We all have our own views on what's ethical and what's not so this can't be an objective statement from the start.
