Isn't this just Google's 2005-2008 Web Accelerator dressed up in different clothes and forced upon everyone? At least Accelerator was opt-in.
Funny thing is that if you visit Google's (still existing) Web Acccelerator download page, you see this:
"We're sorry, but Google Web Accelerator is no longer available for download."
Hopefully the bug that kept Youtube Videos from playing when people used Web Accelerator has been fixed.
I also remember people receiving cookies they didn't want from sites they never visited because of Accelerator.
