regarding your question: Simply because we haven't implemented it. We might do so in the future if there's enough demand.

first off,
let me thank you for taking the time and writing in detail a feedback for us.
I will discuss the bitcoin fees with johnny personally and perhaps cancel them if they aren't required.
Like johnny mentioned, not all day-to-day expenses we agreed to share with you.. the general point is that
owning a file host company is pricey... You have to pay for owning servers, employees, law expenses, etc'...
oh and don't forget! we need to be profitable to survive 
You seem to have a good head on your shoulders and possibly should examine an opportunity to apply for a job in this industry but I digress.
No one can see the future clearly and everyone makes mistakes from time to time... if this happens to be a bad decision that will
have a negative impact in the future we will adjust accordingly... we are dynamic, that's how all successful businesses survive, not only file hosts.
No one is getting "punished" here, your choice of words is very negative and carefully engineered to attack us.
I agree that this industry has seen some ugly events and greedy hosts, but we mustn't hold stereotypes.. remain open-minded
and be objective, see the whole perspective.
p.s: Could you please send me a link to this "blog/portal" thing you talked about?
