A service could work but would need to work around TLS. It would either need to provide you a root CA certificate to install on your systems (bad idea as it would allow them to MITM any website), or a bundle of certificates for the hostnames of the news websites they support (so the MITM is constrained to those domains, but that's fine as that's your intention anyway).
A responsible developer should never supply a pre-configured certificate (though many do exactly that). An unique certificate should be created for the specific installation.
