the delightful ambiguity of English allows us to say such things as "Things that are simple should be simple" and in context of describing design of systems have it understood as Things that are simple to describe should be simple to do.

In this case the ambiguity has allowed them to say That which is free is not free, meaning that which is free to consume is not free to make.

I certainly remember people posting stuff on the internet for free out of their desire to share. I also remember lots of those people over the years shutting down their delightful sites because not having the time to keep doing things for free, nor the money to pay for the hosting or other things like that.
