This includes things like CNAME cloaking, and adding a local JS proxy script so that visits can be sent back to Plausible's servers to make it harder to block for the user. The user has expressed a clear preference for their visits not to be logged, and Plausible (to satisfy site owners who want every visit logged) have done whatever they can to circumvent that.
I get it - it's a business, and making sure the site owners are happy is a big part of making money. But it grates that the whole thing is supposed to be about privacy while ways to get around privacy preferences are baked in.
