PPL License.
A Fake Open Source license, not consistent with OSHWA or OSI definition.
Essentially, PPL is a proprietary consortium in disguise, where the proprietors are the members of a cooperative or collective.
Coops and collectives are in theory nice, but if they are proprietary, they do not contribute to the open source economy. They are not Distributive Enterprises.
Coops and collectives provide clearly-visible economic incentive, whereas Open Source enterprises provide less cearly-visible economic incentives. This does not mean that the economic incentive of Open Source enterprise is smaller - it is just less visible to the uninitiated.
Further, it must be noted that in 4.c. the restriction in the PPL is:
c. You may exercise the rights granted in Section 3 for commercial purposes only if:
i. You are a worker-owned business or worker-owned collective; and ii. all financial gain, surplus, profits and benefits produced by the business or collective are distributed among the worker-owners
