@josh well, if you open up access to your logs (protected via measurements or not) to players you don't want to use them, it's kinda your own fault. Just don't do that. If you web browser passes quotes of your system to the web, it's a bug in the browser, not a problem of the TPM.
Every computing is dual-use, if you so will, I fail to see why this one should be more or less "dual-use" than anything else.
