IE, a polling organization conducts a poll for a vendor with a cost of one million dollars to the vendor to see which is the preferred widget, X or Y. Then, some third party comes along and points out a flaw in their testing methodology, thus invalidating all of the collected data.
That third party has "rendered that data meaningless, useless, or ineffective" and thus could be found guilty under this statute as worded.
This is just off the top of my head with 5 seconds thinking on it, I am sure many many such scenarios could be created. Data is not the same as physical property, you can't just take a property law and replace the word "property" with "data" and expect it to make sense (see the original "mischief" section above in the law).
Whoever got this on the books should be drawn and quartered.
