I'm sorry you had a bad experience, but please don't deface Hacker News by posting rage rants, and certainly please don't post the personal attacks you're alluding to here. Those things break the site guidelines: https://news.ycombinator.com/newsguidelines.html.

You needn't hold any particular view to post here and relevant personal experience is always welcome, as long as discussion remains thoughtful. Your more factual comments in this thread have been fine.
