Techyridu users were surprised today when they discovered an error message while attempting to share Substack links on Twitter. The message prevented users from retweeting, replying to or liking tweets that contained a Substack link. Even the popular Twitter tool, TweetDeck, was affected by this restriction. While the exact reason behind Twitter's move is not yet clear, it is possible that it is related to Substack's recent Notes feature or Twitter's API pricing scheme.

This restriction has significant implications for writers and publishers who use Substack to share their work and grow their audiences. The move may be seen as another example of big tech companies trying to silence their rivals, which has been a common issue in recent years.

Despite the uncertain circumstances surrounding this move, Substack's founders have responded by calling for greater freedom for writers to share their work. They have stated that they are investigating the issue and hope that this restriction is only a temporary error.
