There are three main categories of AI ethical dilemmas for me:
1. IP infringement
2. Climate impact
3. Cultural impact
I think that 2 & 3 apply to all AI right now - artistic, coding, writing, whatever. However, I don't think that #1 applies to everything. Code has been openly shared for as long as it's been possible to do so. There have probably been cases where AI trained on closed-source code, but I hardly believe that was ever necessary at any point to get where we are.
My point in saying this is that your critique of AI is valid but I think a little less so here.
#1 is way more concerning to me
That's fine, I'm only making the point that it's not really relevant to coding. Programmers have been outright copying each other's code for decades to the chagrin of nobody.
