Not ALL tools need to be paid for.

Not all WORK needs to be paid for.

That is correct. Trivial example:

If I say I'll do some work for free the we can assume you don't need to pay for it.

Just like I should not complain if you decide not to keep doing it, when the need to pay for bills arises or I happened to abuse from your goodwill.
