Most (if not all) of the HTML5 potentially track-able values illustrated in the sample web page are inhibited by simply not enabling scripting for the site (and/or for any iframe sub-sites). A Mozilla based browser with NoScript handles that quite well.
If a particular site has HTML5 content that you actually want to hear/view, then you just enable scripting for that content if it will not play without scripting enabled. And just as with enabling Adobe Flash for multimedia content, you just have to accept that one way or another, you are going to pay for that content.
FWIW, I use NoScript and I have Flash setup as "click to play". Any multimedia content I wish to hear/see is only a mouse click away, and the miscellaneous crap from advertisers is either a blank spot on the screen, or a "click to play" placeholder. I accept that if I chose to hear/watch that content, I will either have to pay a subscription fee, or give the sponsor a click-through credit.

We can never have enough of nature.
We need to witness our own limits transgressed, and some life pasturing freely where we never wander.
