YouTube may be throttling video playback for individuals utilizing ad-blockers, based on reports noted by PCWorld on Reddit and other sites. While this remains unverified, comparable assertions have emerged in the past. Previously, users noted diminished video quality and performance while using ad-blockers, an issue that YouTube refuted. Lately, users have encountered a pop-up notification concerning interruptions, indicating that ad-blockers might impact playback. Nevertheless, this does not serve as conclusive evidence of YouTube intentionally slowing down videos. Mashable has reached out to YouTube for a statement and will provide updates if a reply is received. Ads represent a vital revenue stream for YouTube, and employing blockers contravenes its terms of service. Recently, YouTube raised ad frequency for Premium Lite subscribers, who are charged $7.99 per month.
