Yes, agreed.  Once you click 'Like' (or do any such similar action), you know you're making a statement which will be accessible by at least the people who can see your activity.  That may be a controlled population, but it's no longer truly 'private' that you liked something (it may not be fully public either, depending on settings).

More worrying for privacy is that these buttons -- well, the sites they come from -- 'see' what you are reading, what sites you are visiting, BEFORE you even interact with them.  They could build quite a nice dossier from this -- not as good as active 'likes', but quite informative, nonetheless.

Which is why we have the 'active engagement' to convert a third to a first party -- under dnt:1 you are still mostly private at that site until you click 'like' (well, except for permitted uses, of course).
