They haven't been removing GPL code actively, they decided not to take the risk of using GPL version 3 software, so they've let the respective versions of bash, rsync etc. linger at their last released GPL version 2 releases. E.g. Git is on GPL version 2 still (and probably forever), and Apple continues to update that in a relatively timely fashion.

Apple just switched to zsh, which is not GPL other than a few optional shell functions. Expect this trend to continue.
