The article discusses another provider that provides better price/performance than Digital Ocean for certain tiers. With that subject line, I expected a story about billing fraud.
However if you are spending money on some of the higher end Digital Ocean servers you are getting screwed, as they are massively underperforming even compared to just a couple $5-$10 instances.
I'll also note that I am a big fan of Digital Ocean and have been a customer for quite a while now.
