It’s a question which seeks to identify whether the poster is ethical rather than to question the ethics of the synthesizer industry. The thesis statement is from the perspective of an ethical person making conscientious decisions and asking if you consider the ethics of synth manufacturers, but you can just cut out the synth manufacturers, because the underlying question is are you ethical in your considerations of these things.
That’s why I don’t feel comfortable with these types of discussions, beyond the original intent, this is a public forum and judging each other for our purchasing ethics leads to shaming each other for our decisions.
There may very well be a valid discussion to be had about the synthesizer and music industry as a whole in their ethical practices and green policies, just as there was a valid discussion as to the industry and whether or not it takes an ableist position against those with disabilities.
But in this context, the discussion doesn’t work, because we aren’t approaching it from a third-party stance, this starts with a statement about a person’s personal beliefs and their own practices and posits the question “is this something you consider too?”.
I’m just not interested in trying to disentangle the subject from the context. If there is a discussion, I don’t feel that this is the way to have it. Maybe I’m the one who’s wrong, but this is the kind of powder keg I don’t prefer to be involved in, and that’s all I have to say.
