"unlimited" plans are subsidised by low utilization users who are getting less than what they paid for.
to pull it off properly as a service provider, you really need to have a solid understanding of user usage patterns.
one of the big problems that tips the low/high utilization ratio unfavorably is that unlimited plans that are primarily marketed for being unlimited tend to attract users in the high utilization bracket.
so the challenge for service providers is not just understanding users and understanding that ratio but figuring out how you are going to market to, and signup, those users who will be in the low utilization bracket and will essentially be paying for something they won't be user (which is hard to do)
it isn't hard to find case studies of companies that launch optimistically with one pricing plan around unlimited, to then only go back and revise their pricing and break promises because they didn't understand their users and were unable to market to and signup low utilization users.
I really don't understand why some of these low-grade DNS hosting services are so popular when Route53 is available. With Route53 you get a top-grade DNS service that is equivalent, if not better, than the enterprise hosted DNS solutions but at the price of the low-end consumer style services.
I swear by Route53, it is the only service I use on AWS and I have moved a lot of my clients over to it.
OP built an e-commerce platform that raised $1B in a matter of months. Top comment sells bingo card software to school teachers. Who is the authority again?
Apparently that doesn't matter, though. The court case is now about the two witnesses arguing about if the iPad is a unique design separate from all other web tablets, or if it is just a natural progression which anybody would have come up with.
I think what this post is arguing is that it was a natural progression, since others were on the same path at the same time.
I tend to side with Apple, but reading that testimony their witness/expert seems to be grasping at straws in some parts.
