Bollocks. That only applies when paid in the US. Normal commerce would stop if business travel really was only attending meetings.

Yes that is what you say at entry if asked because it's simpler.

Travelling as a tourist managing your own itinerary does have a risk because you're not in a convenient box for Immigration and Customs.

The US is now a no go country for self propelled travellers.

If they ever stopped a business traveller US trade would sink all the faster.
