YouTube has extended its campaign against ad blockers to include third-party apps, which could potentially cause performance issues or display error messages for users accessing videos through such apps on mobile devices, per The Verge. 

"We only allow third-party apps to use our API when they follow our API Services Terms of Service. When we find an app that violates these terms, we will take appropriate action to protect our platform, creators, and viewers," said YouTube.

The move comes as part of YouTube's ongoing efforts to encourage ad viewing or subscription to YouTube Premium, with the platform citing its policies against third-party apps disabling ads to ensure creators are duly rewarded.

Is Blocking Ad-Blocking Apps Legal?

Now, laws regarding the legality of blocking ad-blocking apps can vary between countries. Some jurisdictions may have laws that protect users' rights to use ad blockers, while others may have laws that allow platforms to take action against users who attempt to bypass advertising.

In this case, platforms and websites may have terms of service agreements that prohibit the use of ad-blocking apps. Likewise, they may also take measures to detect and prevent the use of ad blockers, potentially leading to consequences for users who violate these agreements.

Despite potential inconvenience to users accustomed to ad-blocking apps, YouTube remains steadfast in its stance against ad blockers and recommends that users subscribe to the ad-free YouTube Premium as an alternative.
