Modifying the content of others is not a good technical approach for that
business proposition. ​When you modify computer software created by someone
else - without coordination or permission - you create a new piece of
software that the original creator has had no opportunity to test. As a
result such modifications frequently cause failures. Indeed anyone who has
ever written software knows that if you do not test it, then it _will_
fail. So, the modification impacts the ability of the original creator to
offer their customer the service they promised.

The above is equally true if you modify the data the software acts upon.
