Some users are reporting that online videos are taking longer to start when using ad blockers, leading to suspicions that platforms like YouTube may be deliberately slowing down video playback for users with ad blockers enabled.
A thread on YouTube's subreddit has gathered over 200 comments from users sharing similar experiences. Users have observed delays in video playback and prompts such as "Experiencing interruptions? Find out why" when ad blockers are active. Some users even encounter a black screen for several seconds before the video begins.

This issue is reminiscent of YouTube's past efforts to deter ad blocking behavior by implementing slowdowns for users with ad blockers detected. The platform has also encouraged users to disable ad blockers or subscribe to YouTube Premium for an ad-free experience.
While YouTube emphasizes that advertising supports creators and keeps the platform free, users remain divided on whether non-Premium members should be allowed to watch content ad-free with ad blockers. The debate continues as platforms explore ways to balance user experience and revenue generation.
As online platforms navigate the delicate balance between advertising revenue and user experience, the use of ad blockers has become a point of contention. While some users find ad-free experiences valuable, platforms are exploring ways to encourage ad support for creators.
