I wouldn't call NFTs a movement. I reserve that word for phenomena that attempt to drive positive social change. NFTs are just a natural product of the digital scarcity that blockchains provide. There is some overlap between FOSS and NFTs in that they share some technology and process. Both depend entirely on the internet. There are some shared motivations some that are unique to each but they operate in such different ways that I don't see the comparison as being very useful.
