Do you think if a stalker found out about the AirTag silencer from an article they would decide not to use it because the article was critical? They made the choice that publicizing it would lead to harm, so didn't.

Possibly they didn't want to publicize it because they were worried that their platform would lead to more people buying and misusing it?

Streisand effect... why would you write an article about a product you don't want people to know about? What end result would you foresee in doing that, logically?
