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.
I used to work for a company that vaguely competed with them. It was frustrating to have people ask "why does your service cost so much compared to Twilio" and to bite my tongue and say something diplomatic rather than "because we're running an actual business that makes money rather than a VC-funded playpen". Apparently they're not even cash-flow positive at this point?
