Ask HN: Alexa Developer Rewards – has anyone made money?

I'm considering developing an Alexa skill and want to get a feel for what developers are making from their skills, if anything. It would also be nice to know if any of the developers of less-popular skills are receiving payouts from the Developer Rewards program.

Now seems like a good opportunity for Alexa skill development after the number of device sales over the holiday period.

I've read this CNET article: https://www.cnet.com/news/amazon-alexa-economy-echo-speaker-google-assistant-siri/ but am looking for more data.
