Dear nopenopenope,
I would like to reply from a customer side.
I also open source lover and
donater. I would also be happy to live in the "gift economy" when we take all software for free and pay (donate) as much as we want or can. And we would live in such a world but this change will take a lot of time and efforts.
As "gift economy" doesn't work yet I do my best to motivate company I work for to pay for Open Source. Company still love big poprietary VMware, I try to install Proxmox VE instead of VMware and motivate my colleagues to do the same whenever I can. And may plan worked and brought some results! Month ago or so we started another project that is internally supported by higher IT bosses and they agreed to use Proxmox VE in this case. As this is going to be an important production system it was easy to motivate them to buy a subscription. Purchasing department is currently discovering how can we made this purchase in a propriate way (I'm from Russia and our law is quite complicated). This is a small installation (two servers with one cpu socket in each) but this is an important step for Proxmox VE in our company because if we success they will install the same system in Germany and then in other subsidiaries.
Proxmox VE is one of the best open source projects I have ever seen. It is fully open source and is developed very actively and professionally. Last update surprised me a lot at the first, because I started to think that I don't have updates anymore for my five "unproven by higher IT bosses" Proxmox VE clusters. But than I found in the maillists and than in this thread that pve was renamed to pve-no-subscription, so no worries are necessary and we can trust the great Proxmox team. They "want to eat" and of cause I understand this as long as we have sources, we can use it freely and we can pay for support and futher developing.
I would only like to say thank you to the Proxmox Team for the great job they do.
Best regards,
Stanislav
