No, their response did not validate that. In fact, they said the words “it’s not technically illegal”. There is a possibly illegal way to go about it, and a legal way, and no way to prove the difference, but that doesn’t equal technically illegal.

I didn’t feel you deserved the downvotes for your first question, provided it was in good faith. You’re right, like all common misconceptions, it’s best to present clear data wherever we can.
