Civil liberties are generally liberties that are explicitly guaranteed, e.g. in a constitution, while personal liberties are generally anything that's not explicitly banned, so there's a definite shift of emphasis.

Good question. This use of the term has become a popular dog whistle [0] in right-wing circles. It would take a bit of research to see how it was coined in its current form. They know that when you say "personal liberty," you really mean "my liberty is more important than your civil rights."
All you did was link to the wikipedia article on dog whistling. Do you have a source that actually substantiates your claim about the phrase "personal liberties"?
If he meant it to be identical to "civil liberties", why didn't he just say that? Using a less common term seems like it would have to be intentional, so he must have meant _something_ by it.
What have Bezos or Lewis said that indicate 'personal liberties' differ from 'civil liberties'? I don't see it in the cited article.
