Elon Musk is moving forward with dangerous changes to the block feature on X (formerly Twitter). Under the new policy, previously blocked users can still view a user’s public profile and posts, even though they can no longer engage with the content. Musk argues that blocking is ineffective—bad actors can bypass it by using alternative accounts or private browsers—but that’s only part of the story.

The block button is an essential first step for users to protect themselves from harassment and abuse online. It is especially crucial for those facing disproportionate targeting—such as women, people of color, and LGBTQ+ communities. While blocking isn’t a perfect solution, it sets boundaries that are critical for maintaining safety and mental well-being.

Here’s where Google, Apple, and their app stores come into play. 99% of mobile devices in the U.S. run on their systems, meaning they set the rules for what features apps must provide. Google’s terms explicitly require social media apps to offer a blocking feature. Apple’s policies also suggest that apps must allow users to block abusive accounts. When Musk eliminates the block button, Apple and Google need to enforce their policies and remove X from their stores.

Musk’s move has already angered users. Many expressed concern that the new blocking policy forces them to switch to private accounts, even when their public presence is critical for their work. Others have pointed out that blocking has been a first response to mass doxxing, threats, and online abuse. Without it, users have no meaningful way to keep abusers from viewing their profiles.

Our demand is simple: Without a standard block feature, Apple and Google must remove the app from their stores. Apps that undermine safety do not belong on our devices.

Add your name: Demand that Apple and Google take action when Musk eliminates the block button.
