On Oct 26, we sent a formal letter to Truth Social’s chief legal officer, requesting the source code to be made publicly available in compliance with the license.

According to AGPLv3, after being notified by the copyright holder, Truth Social has 30 days to comply or the license may be permanently revoked.

Trump's new social media platform found using Mastodon code

From media reports and individual findings that various people have presented to us, it seems that the new social media platform owned by the former president of the United States, Donald J. Trump, so-called Truth Social, is using Mastodon’s source code with various visual adjustments. The platform has not formally launched yet, but it was made accessible ahead of time. Users were quick to note that the terms of service included a worrying passage, claiming that the site is proprietary property and all source code and software are owned or controlled by them or licensed to them:

@Gargron what do you plan if they refuse to send source code?
@duponin me? send a hacker. and extract source. than put on github publicly. one time i did it with one ios game...

@Gargron didn't i read the software freedom conservancy ... yep https://sfconservancy.org/blog/2021/oct/21/trump-group-agplv3/
so the clock started earlier on compliance?

honestly though, what are the chances they don't just comply with the license? why wouldn't they?

Trump's Social Media Platform and the Affero General Public License (of Mastodon)

An analysis: Trump's Group has 30 days to remedy the violation, or their rights in the software are permanently terminatedIn 2002, we used phrases like “Web 2.0” and “AJAX” to describe the revolution that was happening in web technology for average consumers. This was just before names like Twitter and Facebook became famous worldwide. Web 2.0 was the groundwork infrastructure of the “social media” to come.

@Gargron   Good work  this also shows the advantage of copyleft licences like the  GPL over permissive ones like BSD and MIT, this kind of action would not be possible under such permissive open source licences.
@Gargron good, I hope I can join it with a Mastodon mobile app and not be left out like with Gab that changed too much and broke compatibility.
