Advertisers use uXDT in order to link different devices to the same person and create better advertising profiles so to deliver better-targeted ads in the future

That's not just a horrible violation of people's privacy (and yet another example of why the bill of rights is deficient), but as someone with bat-like hearing (which is how I ended up as a sound engineer) it's yet more noise pollution that I don't want. Perhaps I can sue the industry and buy an abandoned mine to live in with the proceeds.

Another reason to disable JS whilst surfing with Tor Browser Bundle. This article mentions the HTML5 Audio API - Something that should be stripped entirely from Tor Browser Bundle (TBB), but instead stays because TBB shares too much code with Firefox.

Also there's nothing stopping someone simply muting their speakers, or physically removing the speaker from their system if they can (some BIOS chips allow this, aswell as physically turning off the camera)
