Activating windows server 2012 r2 on VDS?

Question

Windows Server

Hello! I order a Windows VDS (Ukraine), a 2003 wine server is free, but it does not suit me, and when choosing 2012 r2 - the inscription you will have to activate the Windows server yourself ... I searched on the Internet, people activate via kms .... and some and they write at all - the functionality will be the same, just in the corner there will be an inscription - activation is required ...
I asked the support, his answer:

Whether or not to activate the OS on the server is your decision, since the server and the OS are exclusively at your disposal.

Who understands this, tell me - will you have to buy a license and without options or can you activate it the old fashioned way or without activation at all? How can they "take for yay ...."?
