It's a strawman because it only makes sense if the one off up front cost is $50k, which wasn't the argument I was making. If the one-off up front cost is $20, then your point makes no sense - your boss would have no issue.

An alternative would be instead of 1 of charging over 100k users $50k, charge every user a one off $20.

I guess it's hard to discuss alternative billing methods without knowing what need to be recuperated.

Thanks for the response, appreciated. Again, sorry for the sassyness.
