It's pretty cool that you have such detailed knowledge into everyone's personal circumstances that you know they all have employment contracts and what the details of those contracts are.
Most people reading this right now are in the US, and the vast majority of US employees at at-will, which means no contract at all. Even for those with contracts, it's a pretty big leap to get to "IP theft" with anything anyone could reasonably work on in retirement.
What made you read that comment and go "they're talking about everyone" instead of "oh, yeah, those people also exist, blanket statements don't make sense in this context"?
