I don't think anyone who really wanted to get into the US would have a problem handing over A social media password. Whether that's a password for an account specifically created to be reviewed by immigration authorities is another matter entirely.
What makes DHS think they would be reviewing a real social media account?
I think this is not about reviewing social media accounts. This is about giving DHS and CBP a pretense to deny entry to anyone they feel like, based on gut feelings, prejudices, whatever.
I would have a problem with it. And I would really want to get into US, possibly, because I work for an American company. But it's not my job to create fake social media accounts, sorry.
I don't think filling out visa applications, in general, is anyone's job (unless maybe you're a personal assistant for someone who travels internationally a lot). It's not about what is and is not your job. If that's what a country requires to allow you entry, and you want to enter, that's what you do.
I am just a normal programmer, not a spy. Visa application is acceptable (I have done that in the past), forging social media accounts is not (I in fact I do have FB account but God knows where the password is).
I think the point they were making was that regardless of how you feel emotionally about giving up specific information, it has no effect on whether a country allows you to enter. So go ahead and do only what you feel is "acceptable", just don't be surprised when you are turned away at the border for not filling out all of the required documents.
