This is a video that was removed from YouTube, and the company account suspended on Twitter, after Trump talked about UVA light therapy. This is a prototype device called the Aytu Bioscience HeaLight. It doesn't exist yet, but they are looking to make it.
The thing about this incident is that the ban-trolls just censored the company because Trump talked about the treatment. That's the level of thinking they have. Trump talked about something. They consider Trump to be an idiot, therefore it had to be false information. Case closed.
On Twitter they just suspended the company page. On YouTube they banned this video.
These are close minded children who work at these companies as censorship trolls. They have a narrative to uphold. Anything that challenges that narrative of reality, no matter if it's real or a theory or technology in development, must go!
The company, Aytu, reported this censorship to the wall Street Journal: https://twitter.com/WSJopinion/status/1254829918904627200
The Twitter page has been reinstated since: https://twitter.com/BioscienceAytu
Here is proof that it was indeed previously suspended: https://twitter.com/MichaelCoudrey/status/1254255771774119936
