Twitter restricts posts featuring Substack after it rolls out rival service

Twitter is limiting any tweets that include links to Substack in an apparent response to the blogging platform's launch of a competitor.

Users reported on Friday that any tweets with Substack links in them could not be liked, retweeted, or replied to.

The restrictions were imposed shortly after Substack, a platform for newsletters, announced Notes, its own Twitter competitor. Twitter also restricted the ability of users to embed tweets onto Substack the day before.
