I guess if you follow the chain of links, you will see that it might be possible to re-enable the cipher type that EFnet is using and make it work. If you want to connect to EFnet anyway, given that the alternative is a non-encrypted connection, it can be argued that any encryption (however compromised) is better than an unencrypted link.

You will need to investigate the ciphers present in the EFnet certificate to know what cipher type(s) to enable.
