You seem confused in Freedom/money...OK,
Conclusion : PROXMOXVE= PAY
nobody say otherwise, you just tell the truth.
People who want to lose their freedom, and continues to pay proxmoxve, since it is no longer a choice.
It is the right of the Proxmox company to get paid.
For others, there are : oVirt, openstack, CloudStack ...
The community just wants the truth, on this one you took the members of the community for idiots.
Sorry for this truth.
First of all, freedom here is the 4 freedom of GPL regarding CODE, what keeps the user and the community free in their computation
To keep your freedom, now you are asked to pay and only if you want "certified" binaries. This will contribute to the ones that gives you AGPL code that you can inspect, check, learn from, patch etc.
For others, there are : oVirt, openstack, CloudStack ... until they realize that need money to keep the development, so will ask you. Or will stop the development. Or have users that donate enough money
If you want Free(dom) code, as I want, I think what proxmox asks is a modest issue that worths a lot
If you want Free(dom) code and not pay, you can choose other Free project hoping they will get money from someone else but you
If you want free (no pay) only, you can go to some proprietary solutions
If you don't support Free software development now, you could have no more choice in the future than IT slavery
