Sorry, but drive-by philosophy is not applicable here.

YouTube developers single out adblocker users and taunt them with an "Experiencing interruptions" toast prompt that locks the video stream for ~5 seconds. Curiously, it contains a link to the YouTube Help Center, to the section fragment "#check_ad_blockers". In other words: "yeah, we know you've got uBlock Origin enabled, enjoy the speedbump".

Player base.js:

    api.XL("innertubeCommand",{openPopupAction:{popup:{notificationActionRenderer:{responseText:{runs:[{text:"Experiencing interruptions?"}]},actionButton:{buttonRenderer:{style:"STYLE_OVERLAY",size:"SIZE_DEFAULT", text:{runs:[{text:"Find out why"}]},navigationEndpoint:{commandMetadata:{webCommandMetadata:{url:"https://support.google.com/youtube/answer/3037019#check_ad_blockers

I have noticed this but have been unable to explain it until now.

So that's what it is! I've never seen the toast message, but I had a suspicion it was intentional on YouTube's side considering it doesn't occur in Chrome. Sadly I don't see a work-around in that reddit thread. I wonder if someone has a violentmonkey script for it.
