The author does not even bother to mention which video, which browser plugins he is using, or even what domain he is on. I am skeptical of these claims with no attempt to reproduce.<p>I would like to know if another browser would show the original comment or the altered one. Because the comment shows up and is then altered after the fact, I would blame a translation plugin on the client side.<p>I could see a poor-quality plugin being fooled by a different-language version of YouTube and auto translating.
Honestly I'd be more inclined to write this off as a bug with Polymer.js or something rather than jumping to a conclusion from the YouTube comments like "Say goodbye to free speech" -- It's much more plausible to be a technical issue than an attempt at controlling the contents of <i>YouTube comments.</i><p>The guy says it was an amalgam of his previous comments he'd made that day and I'm sure if you have a channel of his size, you're likely to have YouTube open for quite a while, and since it's an SPA, you could get all sortsa concurrency bugs or whatever.
I guess the main critique here would be the question of authenticity. How can you prove that it was actually youtube and not some homebrew lookalike site he cooked up?<p>With that said, I'd like to add the obvious "BIG if true"
