Defining some terms: Alice, Bob, the company, and GCHQ (Eve).
Alice sends Bob stuff, via the company.
GCHQ sends RIPA requests to the company, which means that GCHQ get Alice's communications. Neither Alice nor Bob are aware.
So, a new scheme where Alice and the company need keys to decrypt means that GCHQ send RIPA requests to the company, and to Alice. Now Alice, and the company, are aware of the RIPA request. Bob isn't. But at least Alice can stop sending things to Bob.
