Permission from the original programmer thru the Open Source License granted so you can run the software. 
A crypto currency is not software. It is a protocol, written on paper, that anyone can implement in software. Usually, the guy (or girl) writing the paper also puts some working software up, but that is secondary. You don't need the software. You only need the paper of the protocol. Then you can write your own software to use it.
Look at this guy, using bitcoin without running software from somewhere:
http://www.righto.com/2014/02/bitcoins-hard-way-using-raw-bitcoin.htmlYou don't need core or BU or whatever software. You can do it the hard way, using some python scripts and a command line interface. You only need the detailed protocol description.
The use of Pythagoras' theorem is permissionless. Anyone can use it. The same for an open crypto currency protocol. It is nothing more than a more involved kind of statement. From the moment that you can read it and understand it, you can use it.
In the end, the "permission" is in the intelligence needed to understand it and code it, but again, you are stretching the notion to make it meaningless.
LOL,
I wait for you to write up your blocks on paper, your blockspeed will be what 1 year per block.

Someone else wrote the original code , granting you
permission to use it thru the Open Source License.
The fact is , everyone is using the software and they have received permission to do so.
The word permissionless implies , No permission needed , but the facts is permission was granted thru the open source license.
Your use of the word permissionless is the one with no basis in reality in which we reside.
By your statement , if I give away a PoS coin for free, it is also permissionless.
Or is that Contradiction in your thought process too much to bear.

FYI:
As far as this Reality goes , all crypto is permissioned.
