Hakuna matata is a Swahili phrase, which after it was introduced in a song in the Disney film The Lion King came to mean both "no worries" and "no problem".
Some people came up with elaborate hypothetical scenarios where using the more restrictive GPL licence will be advantageous instead of the permissive software licences which I prefer to use for most of the software which I originated. However, I was non-plussed by them and said I will be “OK with it”. People did not violate my trust, because I entrusted them with the power to do so, which made them feel empowered.
I believe that if the great Saladin was alive today and was a developer of open source software (which is not as farfetched as it sounds), then he too would prefer using permissive licences when he could help it.
I met Wilfredo Rodriguez on freenode, and he notes that he uses the public domain ( CC0 ) for most of his photos, so people can use them even without being legally required to credit him (much less to pay him). Nevertheless, many of them do exactly that.
