I noticed this question was locked by W5VO over a content dispute. But I'm not really sure what the dispute is about. Can someone shed some light on the lock?
In terms of mod tools, this is an example of only having a hammer to deal with a situation. Specifically, the user in question wanted to delete their question. The system won't allow you to delete your own question once you have answers, so they edited the question to remove all content. These changes were then rolled-back. This went back-and-forth a few times, and so I locked the page to keep the question intact.
Also, "locked" does not mean "closed". I don't intend to close this question for the very reasons you mention.
This could have been resolved much more simply if someone were willing to state the answer as a sum of products as requested.
It's the sum of a single product of a single input...
And no, that is not really a joke, since that's what the implementation really would look like if you have a sum-of-products type PLD.
