This is an extension for a $50 a year service for sending articles to your Kindle that as far as I can tell, is not demonstrably better than the free extension or using a service like Instapaper or Pocket. So yeah, sorry they won't feature your extension for an extremely-overpriced service dude, but crying about it on Hacker News in an attempt to drum up publicity doesn't make me sympathetic.
