If you consider pulseaudio, systemd and not being able to play mp3 traditional. Also, they used to fuck with encryption in some way, not sure if they still do it.
In the end, do you trust more Poettering or Debian or Ubuntu developers?
Only a little sarcastic; RHEL and Red Hat's historic treatment of CentOS had a lot of echos of Oracle's treatment of similar projects. They've gotten a little better in some regards (now own CentOS and seem to care about it) and worse in others (the of marketing and politics instead of merit).
What? Red Hat didn't treat CentOS badly: they happily let people make trademark-less respins of their OS per the license and didn't try and stop anyone from doing so.
