Tell that to Sunny Singh, the other Vimeo user who was featured in the Verge article, who did the math himself and had to admit that he was costing Vimeo $2500/yr.
If so, he is not saying that he is costing Vimeo $2500/year, he is saying what amount of bandwidth he has "consumed"/"produced" from Vimeo, which for sure doesn't cost Vimeo $2500/year, as otherwise they would be bankrupt by now. They pay static sums for the internet connection, no TB/$ crap that people using cloud are used to.
A customer shouldn't really need to concern themselves with the profitability of a service provider though. The price Vimeo demanding is reasonable - what's not reasonable is hiding that prices could increase, and being basically as opaque as possible about the conditions to trigger that increase and what the increased cost was.
Your comment is false. Singh did an analysis and used the analysis to negotiate to a $2,500/year rate. He didn't "admit" anything about what it could be costing Vimeo.
