My question was not so much about whether GPL automatically equates to free – I am well aware it doesn’t. Neither was it about whether a “commercial” plug-in can be released under GPL.

My question was more in respect of constraints that are imposed on commercial plug-ins which apparently contradict the GPL licensing model. e.g. limitations of use, no right to distribute/modify etc.

The link I provided – I’m not sure whether you read it esmi – outlines a stance being taken by WordPress against theme providers. My question was if themes are not exempt from the WordPress licensing model, then how & why are plug-ins.
