I agree absolutely people have a responsibility to others...
There's are many models I don't display online because they have asked me to only include their work in published books, I respect that.
That said, I don't ALWAYS have a release, but do often if it's a long term thing and I'm shooting art content.
But the fact is, owning them and displaying them are different.
And I feel that I should not be told I can't own something once freely given because they changed their minds about it.
That's like saying if I had sex with someone, and then next week or next year they decided they didn't want to have sex with me, that they could have me charged with rape... I'm using this extreme to illustrate the point...
It's a slippery slope... Next the court will say I can't own photos of my ex in clothing because she doesn't want me to look at her anymore. Or that all family photographs with Aunt Judy in them need to be confiscated an destroyed because they are having a family fued...
It's ridiculous. You made your choices in the past, if you believe you made a mistake, learn from it and move on, but you can't change the past, and you shouldn't be able to take things away from people that were freely given.... Simply because you changed your mind later...
