Former President Trump’s new social network might be in hot water before it even launches. Mastodon, a free social media framework, alleges that Truth Social is passing open source software off as its own and has given them 30 days to fix this. If it doesn’t fix things by the end of next month, things could get messy.

In a post to the Mastodon blog, founder and CEO Eugen Rochko explained that the problem is not simply that Truth Social uses Mastodon, but that it does so while claiming ownership over the site’s code. People inspecting the code of the pre-launch site last week found it was very clearly using Mastodon’s code without acknowledgment.
