I am trying to sympathize but I agree 100%. You seem to be complaining about being inconvenienced for a few hours as a result of your inability to be on-point with your profession for the few seconds that it matters most during your re-entry to the country. The world is full NOT bright people. You can't really expect them to know the difference between software and web developer. You just need to solve for that and make sure you make it easy for them to let you back in.
I did not write the article. It's not about being 'inconvenienced', it is entirely about the incorrect opinion of a border guard causing you to lose your job, income and whatever personal connections you have established in the USA even if you have been doing everything correctly.
Typically you have to pay for these 'inconveniences' with another flight (that you pay for), immigration lawyers and so on if it gets really bad. There is a complete power imbalance in that situation and due process, if any, is minimal at most border crossings. ANY record of shit going wrong at the border will result in you getting extra attention EVERY time you cross.
