I think it is interesting that the IRS treats certain workers differently:

"This section shall not apply in the case of an individual who pursuant to an arrangement between the taxpayer and another person, provides services for such other person as an engineer, designer, drafter, computer programmer, systems analyst, or other similarly skilled worker engaged in a similar line of work."

(this was cited in the letter)

Here's a little bit of background about that provision:

I'm highly amused that the last name of the guy who wrote that piece is "Henchman."

To be fair, it's not that the IRS has decided to treat these workers differently, it's that Congress has instructed them to through the laws it has passed.
