That story starts with her being refused entry to Canada. So, there's more than just "US border guards mean" going on here.
Then it turns out that she was using Workaway, which is like AirBnB or Uber but for foreign labor on tourist visas. They don't tell you that you need a work visa to work in another country [1], but you almost certainly do anywhere you go, not just the US. The woman in the story was working in exchange for accommodation, which is legal for citizens but not for aliens: work permits and visas exist to deter illegal immigration. She didn't have intent to immigrate illegally, but the scheme under which she entered the country was illegal, and she confessed to it in her statement to the border guards.
The real bad actor in this story was Workaway, and I'm surprised they haven't been shut down yet. They offer an alien labor arrangement that is almost certain to get you detained if caught with the wrong visa, don't give you advice on visas, and aren't there to help if something does go wrong at the border. I doubt there are many countries who welcome their alien labor arrangements, either.

You're right. But as someone who has been internationally nomadic for 15 years, I don't think most people understand how many tens of thousands of people travel internationally on tourist visas doing work exchanges to be able to afford their tourism. It's commonplace. Yes, it's usually illegal. Most countries don't dedicate a whole lot of resources to enforcing that. And in most countries, getting caught working while on a short term tourist visa will get you 1) a fine 2) deported (probably self-deported, on a commercial flight) and 3) banned from re-entering the country for a period of time.
What does NOT usually happen in these cases is 1) having a full body cavity search 2) being shackled in the back of a van 3) having your phone confiscated 4) being forbidden from contacting any family or legal representation 5) having your clothing cut apart 6) being transported to a different city without being informed of what is happening 7) being cut off from access to your foreign funds 8) being detained for 19 days.
The notable thing isn't that she broke the law. The notable thing is the cruel and unusual severity of the punishment for a relatively minor visa violation. Typically, when countries punish tourists so severely for what should be a slap on the wrist, tourists stop wanting to go there.
Nobody is denying her visa wasn't correct for the type of work she was doing. But that doesn't justify the treatment she got. Nobody but violent criminals should be treated like this.
This was a paperwork issue and should've been resolved with paperwork - refusal of entry and a plane ticket back.
