Seems like he just cherry-picked the negative comments. That'd be fine, but choosing not to mention this kind of hurts his argument. (Could have titled the article "Six Years of Twilio Doubters on Hacker News" or something more clever than I can come up with.)
The comment he gives for "Twilio Launches UK SMS" is from the bottom of the page with one or more downvotes. Meanwhile, the first comment on that page says "Awesome work Twilio, been looking forward to being able to play around with SMS as much as I have calls without having to use a US number."
It's no secret that commenters on the internet produce a lot of lame, negative comments. If you filter for those, you're basically trolling yourself at a meta level.
I bet if you collected the best and most insightful comments about Twilio over the same time period, you'd find they go further in the positive direction than these ones do in the negative.
> Keep doubting! And don't forget to crap on any new thing that gets launched.
For every post like this, you get two complaining that HN is a bunch of cheerleaders for XYZ. I don't know if the positive/negative balance is quite right on HN, but I do know that it's not all "haters gonna hate"-worthy. Further, some of the highlighted comments are pretty factual and useful. For instance: Authy is/was a fairly sloppy app, and it managed to lose my data during one of its many upgrades.
