On that website, Tony promotes guidelines “for making it easier, faster, more affordable, and more maintainable to build web software.” [...] The guidelines include the following:

• "Prefer vanilla approaches" wich is contrary to "Use libraries that leverage HTML attributes"
• "Use HTML attributes for styling and behavior" wich is contrary to "Prefer naked HTML" (and common sense since CSS exists)

This Tony guy seems to not have thought about this enough.
