Hello @earthcustodians,
It does seem that we have very different perspectives and opinions on this topic. Everything on the internet is there to be used. Everything on this plane is there to be used. But it is a matter of respect to the creator, to give credit for their work, should it inspire you or should you feel the need to use their work in part, to better express a point, concept or ideal, amongst other expressions.
I feel that this is an inner feeling issue. I feel that it's right to credit, source and link work, because my ego doesn't have to pretend to be the creator, or I don't fear people thinking less of me for using the inspirations of another, because they inspire me and I would like to transmit that to other folk.
This is just how I feel, of course, and I do get that you feel differently, but one have to be careful that one is not creating reasons, excuses and righteous perspectives, based on not being able to accept criticism from one's peers, in order to justify one's stance.
Belief is another discourse, but I do feel that the word copyright might not be helping here. We are talking about intellectual property and uncopywritten works that are creted from personal work and input, study, research and composition. I feel better in myself for giving credit and support to those that I look to for inspiration, help and elucidation.
Maybe we should agree to disagree, but I never understood that and I feel it is always better all round, to discuss such matters as we can all learn from doing that.
Thank you, for your comment, @earthcustodians
