Is a non-party deponent bound by the rules of civil procedure?

The rules of civil procedure limit the manner in which a party may record a deposition. However, it does not appear to me that they impose any limit on a non-party deponent. Secondly, even if the rules did prohibit a non-party deponent from recording, how would a non-party be bound to the rules of procedure. The subpoena itself compels the deponent to make himself or herself available for questioning, but doesn't seem to bind the deponent to any specific set of rules, and I don't understand the rules of procedure to be binding law upon citizens at large who are non-parties.

The rules do seem to say the court may impose sanction on a "person" who impedes the examination of the deponent, but I don't see how recording, if permitted, would be such an impediment.
