I would probably list out a series of symptoms of large businesses that don't qualify for my non-corporate license.

• The company itself, its owners, executives, board members, employees or any other persons associated with the company has spent more than $100 on lobbying since the invention of the written word. To include a middle manager that worked for the company for 2 weeks, quit, and then later went on to become involved in lobbying.
• Any executive, board member, manager or such person currently or has ever had a contract that features any clauses that could be described as a "golden parachute."
• The company has ever engaged in anti-union activity.
• The company has ever outsourced jobs overseas because labor in developing countries is cheaper. Hiring outside one's home country seeking better expertise ie "We contracted with a German machine shop because the sample work they turned in was of better quality" is okay; "We only have to pay Vietnamese teenagers 40 cents a day" isn't.
• The company publicly trades stock. That is to say random people mostly stock brokers and banks that don't actually generate any value for society pays a little money and then expects dividents in perpetuity like ticks getting fat and bloated with the blood of higher life forms. These people may not financially benefit from my work more than I do.
• The highest paid person who is in any way on the payroll of the company is paid more than 20 times the lowest paid employee.

That's probably a good start.
