Except for the website owners whose copyright they may be infringing.
Some of the 'carrots' are useless though:
* An upgrade to a faster broadband package at no extra cost
I've been told that I've already got the fastest my line can support. So has almost everybody taking ADSL broadband.
If that's not actually true, then I'm afraid Trading Standards need to get involved, and the ASA as well.
* £1 off monthly broadband bills
That might actually work. Well done - but make the number bigger.
* £1 cashback per month
Cashback deals are generally bogus. The Trading Standards have already investigated a lot of them...
* A cut of advertising revenues
Even better, as long as the minimum 'cut' is £2 per month.
* A free premium technical support line
The only tech support I've ever needed was when BT have screwed up.
* Free music download vouchers
I don't download music. Which store would they be for, anyway? Almost all of them stick annoying DRM into the files so you can't pay them on %device_of_choice%, and have to use proprietary software/hardware.
* Free anti-virus software
I already have it, as does almost everyone sane. There are a multitude of good ones, such as Avast, AVG and a few others. The 'big two' paid-for ones are useless anyway - Norton crashes my PC every time I start up a couple of graphics-intensive applications, and McAfee is incredibly slow.
* Parental content controls
This is shortly to be a legal requirement in the EU. Don't try to get me to pay for something the EU has mandated you to provide for free!
In short - too little, too late.
If it rolls out it'll be amusing to see the first copyright infringement lawsuits from webmasters though.
