Plausible is a third party that logs visits for analytics purposes. An end user expresses their preference (eg, with some sort of blocking browser extension) that the site doesn't send details off to a third party. Then the analytics service provides an easy way to work around this preference, and if that's blocked again then they provide another way, etc. They explicitly work around the end user's choice.

Why does it matter what the reason is for the end user's preference? Or if the data is being stored in a way that's currently difficult to deobfuscate? It's ironic that the whole push is "end user privacy", ie something that benefits the end user, but multiple workarounds are offered when the end user (for whatever reason) doesn't want their visits logged on a third party.
