A server like Nethserver is much more complicated than a simple bare centos, we talk about postfix, antivirus, sambaAD, VPN, sharing point…and a lot of modules that you can simply install with a left click…This freely, except if one day I can meet you in the real life to share a beer.
Even if you go to centos, you will have the same regressions/changes because nethserver is a clone of centos
I shared with @davidep Friday, he was so sorry about the community issue on the centos changes, but at the end, how can we avoid this, test all pre-beta before and try to fix bugs.
This needs money, hence the subscription, because a lot of people are needed.
I have had the chance to visit the nethesis office, it is about ten developers, not all the time on the community version, because they have to sell service to customers.
