I can think of two explanations for that off the top of my head.
The first is that people only recognize the problems with the things that they're familiar with, which you would kind of expect.
The other option is that there's a difference in the thing that people object to. My impression is that artists seem to be reacting to the idea that they could be automated out of a job, where programmers are mostly objecting to blatant copyright violation. (Not universally in either case, but often.) If that is the case, then those are genuinely different arguments made by different people.
