The new license terms for RHEL are structured to stop subscribers from exercising their rights under the GPL. For now they are still providing source code albeit in a less convenient form, but technically they only need to do this for GPL licenses packages and they could remove code for BSD /MIT / Apache licensed packages.
Do these developments make you more.inclined to distribute your software under a copyleft license or are you happy with something more open?
No, it’s ultimately a product of all the community that works on it. Red Hat doesn’t drive the ship.
