This may be an example of the "no true scotsman" fallacy. You're saying no true game developer would use social exploitation in this way. Implying that any game developer who does, isn't in fact a game developer.
The problem with this approach is that it absolves any such person who considers themselves a true game developer of the responsibility. I think it's more valuable to view social engineering as the dark side of game development, and look for ways to minimise it.
It's similar to the way software developers often come up with (or are asked to come up with) "dark patterns" to manipulate users into signing up for stuff or buying stuff without realising it. It's our responsibility as developers to recognise when this is happening and actively work to stop it.
