I'd say it's likely not due to any shenanigans, but simply because HN readers in general love eInk devices.

That said, I do which there were more players in the market. If you want an Android powered e-Ink device, you don't have a lot of options at the moment.

I don’t think flagging a post for that is a good use of that system, because the submission isn’t breaking the rules. But a comment in this thread as a reminder seems reasonable.
