It seems like a running that their primary competitor (Plivo) is ahead on features, and has better prices. I think those are completely fair criticisms of any company. It's a little strange that this compilation goes to great lengths to never mention the competitor by name.
you can click on the links and see they are each about a different competitor.
"Hater News" heh... yeah sometimes people do tend to hate around here, but it's nowhere near as bad as Reddit.
