ULA is a private, commercial entity, but most of what they do is paid for with American tax dollars. As such, as a taxpayer I prefer having photographers not make free money off of the taxes I paid because that's not what I agreed to pay taxes for.
Note that this new agreement doesn't prohibit independent photographers from selling for educational purposes ("work[ed] for the media") and otherwise most(any?) non-commercial purposes ("post their work on social media", et al.).
I am 300% okay with that as a taxpayer paying for the things being burned into film.
