Re: twitter.el, anyone?

twittering-mode relies on data called Root Certificates.

Here is an example of a Root Certificate:

-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----

These certificates are provided by Symantec.

When redistributing them with their software, developers have to agree
with the Root Certificate License Agreement that can be found here:

http://www.symantec.com/content/en/us/about/media/repository/root-certificate-license-agreement.pdf

Developers don't need to sign the agreement, they implicitely accept
it by using and redistributing the certificates.

My reading of the license agreement above is that using Symantec
certificates in a software creates a lot of constraints for the
developers and that these constraints are not compatible with using
them in a free software -- but I may be wrong and I will let someone
else double-check.

In the meantime, I told the twittering-mode maintainers about this
problem and they will check themselves, hopefully coming up with
other certificates.
