A relevant operator includes telecommunications services, defined in s193(11) as "any service that consists in the provision of access to, and of facilities for making use of, any telecommunication system (whether or not one provided by the person providing the service)"
This has been slightly changed, now that the IP bill is no longer a draft: http://www.publications.parliament.uk/pa/bills/cbill/2015-20...
The above draft is now re-written as:
s217(4)(c): "obligations relating to the removal by a relevant operator of electronic protection applied by or on behalf of that operator to any communications or data".
There's an appeals process, but the gist is that they're not outright banning backdoors. But if they come knocking, you better find a way to remove any protection that's there. Which is rather chilling.
