After some research, I discovered that YouTube offers a
privacy-enhanced way of embedding videos. Instead of linking to
youtube.com, link to
youtube-nocookie.com, and no
data-collecting HTTP cookie will be sent. This is Google’s way of
providing GDPR-compliant YouTube videos.
Now that Safari is including tracker counts and blocking ad trackers by default, I ran into this when I embedded the video for The Talk Show Remote From WWDC 2020 this week — it doubled the number of “trackers” Safari flagged on DF from 1 to 2. No more.
(The remaining tracker is Google Analytics, which I’ve been meaning to replace for a while. On it.)
