Mastodon's Founder Says Trump's New Social Network Is Just Mastodon

'Truth Social', which will launch officially later in the year, is seemingly using Mastodon's codebase without credit.

Its terms also say that “all source code” of Truth Social is proprietary. That might run afoul of Mastodon’s own license.

“The main thing is that Mastodon is free software, released under the AGPLv3 license, so anyone can use it—provided they comply with the license. The main part of the license is making the source code and any modifications to it available to the public,” Rochko told Motherboard. With Truth Social saying that its code is proprietary “that would be a problem, as that would indicate a license violation,” Rochko added.
