This article makes me truly appreciative that my product/service is not essientially a "commodity". Absolutely no disrespect intended for BackBlaze, as they have obviously gone the distance in adding value to their core "we store data" product.
That said, I generally find it easy to raise prices. Indeed, price discovery is "fun" in my tiny tiny niche. Basically, I just increase the price every time a new customer signs up. I honestly think this is completely fair to both past and new customers. Sign up early and you reap the benefits of lower cost. Sign up for a longer term and you keep those benefits.
It's a struggle with inflation, and I strongly appreciate the argument in accounting for it. It is so obviously real, yet customers seem to have an extremely hard time wrapping their heads around it.
