Companies that use primarily contractors make regulators uncomfortable, and their general antipathy to such ad hoc arrangements is pretty well known. It's much easier to regulate and collect taxes from, and admittedly to protect, people who work for large companies the government can exert control over. So these challenges will keep coming as long as complainants can be found. The fact that they can be found easily enough is also interesting, and I suspect that what is going on here, at least to some extent, is that the "early adopter" contractors who are more independent and seek fewer controls are soon augmented as the business grows by people who are attracted to the good things they hear about, but at the same time really aren't lone-wolf risk takers, and really don't want to provide for themselves.
