A Legal Question
The donate page for Wordpress.org says, "The WordPress Foundation is a 501(c)3 non-profit organization (Federal tax ID 20-5498932)."
I'm not a programmer, my coding is so ugly that it kills tardigraves, but I did incorporate a 501(C)3 back in the day,
It appears to me that Mullenweg, by using the not-for-profit to enrich his for-profit company is engaging in inurement, which is a violation of IRS regulations on the subject.
https://www.irs.gov/charities-non-profits/charitable-organizations/inurement-private-benefit-charitable-organizations
"A section 501(c)(3) organization must not be organized or operated for the benefit of private interests, such as the creator or the creator's family, shareholders of the organization, other designated individuals, or persons controlled directly or indirectly by such private interests. No part of the net earnings of a section 501(c)(3) organization may inure to the benefit of any private shareholder or individual. A private shareholder or individual is a person having a personal and private interest in the activities of the organization."
This sounds to me like a violation of black letter charity law, though I am a mechanical engineer, not a lawyer, dammit. (Yes I just went Dr. McCoy)
