Note that systemd was not pushed to anything: several members of the various open source communities appreciated their features and considered it worth to be used and even made the default. Please read the long, technical and detailed discussion Debian had before choosing systemd as their default init system while still providing sysvinit as a supported choice: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727708
Also Intel developers didn't design GNOME 3 for touch screens. Sure, Clutter development was at some point carried on by Intel, but most of the GNOME design comes from RedHat and volunteers. That said, it's true that GNOME cares for keyboard, mouse and touch interaction: and I'm very happy that they care about touch, thanks to them using the touchscreen on my new laptop has been a pleasure.
To answer your concerns, both systemd and GNOME see a big investment from RedHat in their development, but the developers are influencing RedHat's choices more than the opposite. Keep also in mind that a huge number of contributions still comes from non-RedHat developers for both systemd and GNOME, at the moment there's no risk that the company will drag these projects where their maintainers don't want to go.
