Putting the panopticon server in a building that says Apple or Microsoft at the entrance hasn't solved anything. Corporations are hardly more trustworthy than the government, can be coerced into doing the mass surveillance under gag orders, could be doing it for themselves without telling anyone, and would still be maintaining servers with access to everything that could be compromised by organized crime or foreign governments.

Which is why the clients have to be doing the encryption themselves in a documented way that establishes the server can't be doing that.
