This is trying to shame clients into supporting Delete.

Great idea, comrade! 

 Some like redefining terms, which is essentially deception.

Thats how they strategically exploit the pattern of commumication of those who are factual and care about accuracy. 

 To your last question:

Its rich coming from someone who feels no shame about lying to end users :)  

 Advocating to show users a Delete button, which doesn't actually delete 

 You're pointing out factual problems.

He's responding like a SJW: with no actual rebuttal, instead with shaming tactics, redefining words ("it works" lol), character attacks (aspy) and just assuming the higher moral ground (let the people delete). 

 Yes delete is vital for privacy, which is why a "sometimes working, sometimes not" delete is so much worse than no delete.

Expectation management.
