The video is a no-issue. Patent and competition laws exist to encourage and promote innovation, not to discourage them. If your primus about the video was valid it would discourage a company from giving any information out whatsoever. That in turn would discourage investors from investing money on new and/or improved innovations and technology. Especially if there was even a small chance a company might not be able to patent their work because of a technical legal issue such as a video of a company's progress posted on their web-site.
