Let us say I am a bank. I have thousands of customers who use online banking for a variety of reasons. One day, as the CEO and decision maker for the company...I decide that to protect my users I must disable online banking as it is too easy for people to be keylogged and have their accounts hacked into.
So guess what, I am going to just pull the plug.
Oops. I just lost a large amount of business because my customers relied on online banking, and had no notice to prepare for the change.
If you're going to be hypothetical, at least actually come up with a situation that isn't massively different in a way that was clearly chosen to favor your argument...
How about you try a logical analogy, instead of an intentionally incorrect one?
Let us say you are a store. You have thousands of customers who order online with all the gift cards they got given for birthdays. One day, you discover that UPS is stealing large numbers of the packages you ship out, so you drop them as a carrier.
Gee, you look like a lot less of a jerk in the hypothetical when your decision was based on someone else's action...
