I'm finding the "outrage" about #RHELs change of subscription terms very weird. Open source development happens in the #upstream repos and the only people that really care about the source for downstream binaries are those with the binaries. #redhat's limiting of RHEL clones does make it slightly harder for projects to ensure #ci loops run on those distros. However Red Hat are big enough to take on those responsibilities in house and report back when regressions happen.
@stsquad The difficulty is being able to use a stable distro for things without wanting paid support. CentOS (and descendents) were useful for a bunch of people who just wanted something for a non-critical host. It was also useful to people who had their most critical boxes on RHEL subscriptions and CentOS everywhere else, but didn't need to know two systems. Having a restriction that says you're not able to distribute free source is just nasty.
