 This is a follow-up to #41784.

 **Summary:** The “do not track” (?dnt=1) embed parameter is currently
 being automatically applied to all oEmbed requests for Vimeo videos,
 seemingly those embedded in self-hosted versions of WordPress only.

 We’ve traced this back to the change made to address this ticket #41784
 (https://core.trac.wordpress.org/changeset/41345) The reason this is only
 coming up now is that Vimeo only just recently added oEmbed support for
 DNT- https://github.com/vimeo/player.js/pull/403

 The issue with this WordPress change is that adding a DNT parameter to
 Vimeo embeds is intended to automatically block'' all'' tracking in the
 Vimeo player, including player statistics. Stats are a big feature of
 Vimeo which many users rely on, so adding this parameter is currently
 leading to user confusion when stats are not collected. Many users aren’t
 aware that this parameter is being added for them by WordPress, nor do
 they understand the implications. Vimeo support currently receives 1-2
 support tickets from users a day who are affected by this change and
 unaware of the parameter being added by WordPress, and it's ability to
 disable stats.

 Documentation for the DNT parameter on Vimeo can be found here-

 Parameters

 **Proposal:** WordPress should **not** automatically append the DNT
 parameter. Users should have the option to add DNT if they determine that
 it fits their needs.

 Note that unlike Twitter (which was mentioned in the initial report, the
 Vimeo player does not contain cookies which are unessential to player
 functionality (like saving language preferences or viewer statistics) It
 does not track  'non-essential' cookies like google analytics and other
 third party cookies (used for ad serving, etc).
