[whatwg] Chipset support is a good argument

[Kristof Zelechovski]

Small authors are hardly an alternative to YouTube because they use YouTube
(or a similar service) to publish their content.  Neither do YouTube publish
most of the stuff on their own; they only allow the authors to do it using
YT technology.
In short, if you do not have the know-how to serve your video content, you
will just use YouTube and never bother.  And if you do have, you will not
begin with reading the HTML specification either.
