It was submitted by a volunteer, Leigh Scott and I took up the review voluntarily.The major opposition came from another volunteer, Christoph Wickert who was concerned about sustainability and violation of packaging guidelines regarding forks and we discussed it with the packaging committee and it was eventually approved by another volunteer, Dan Mashal. The delay was partly my fault since I took up the review and didn't finish it up quickly since I was focusing on release specific tasks at that time and we also had to get the packaging committee approval and the reviews themselves took time.
systemd was submitted by me and approved by another volunteer.
It became the default after approval by FESCo (a fully elected body btw) which did delay it by one release despite having a number of Red Hat employees in it. So if you are looking for favoritism you have picked the wrong examples. Are there other packages submitted by Red Hat employees as part of the job? yes but the important point is that the process is not designed to be any different regardless of who you work for.
