Author here: ethical concerns are legitimate and they don’t require contact. You’re right that the center is not just skewed because of the arguments I made but also because of other factors such as the availability of money and time.

I’m not disputing that. The argument in the article is a much narrower one: use. It’s that without use, one’s view of how it behaves in practice is second-hand from the people that engage.

If all ones criticism is confine within ethical or monetary concerns then this article does not apply.
