A lotta words to describe what's inevitable under a capitalist model of software creation and distribution and an ideology that limits itself inherently.
It seems like Perens is discovering what RMS already predicted a long time ago (ironic considering he quotes him), that Open Source will fail its users in terms of freedom (i am not speaking about Open Source as a development model but a political movement and collective who use the term to define itself).
The Open Source community has shown itself to be unreliable in defending our freedom. The lax attitude toward nonfree tooling like Github and copyleft licenses has shown itself to create issues like the ones mentioned by Perens. It's a bad look when hackers are forced to use nonfree software to participate in open source development when libre solutions either exist already or can be spearheaded by these same hackers (source hut comes to mind).
The GPL enforces itself and hunting companies that violate the GPL was never the goal (when they are sued by the FSF, it is only so that they publish the source code by the license terms). The purpose of the GPL was to create a community of hackers to build software under a protected copyleft domain. These problems that perens mentioned are applicable to the pushover MIT/X11 license which unfortunately has lured hackers into believing that the current capitalist tech field would respect them (EEE and enshittification debunk this). Pushover licenses were a specific strategy for certain pieces of software (miniscule libraries, open file formats to replace closed/patented ones) but have been overused to the point of meaningless.
TL;DR a movement that appeals to capitalist corporate interests rather than emphasizing freedom on ethical/civil grounds will be limited by that same system.
The goal of the hacktivist struggle was always to create software that protects the users freedom as nonfree software is inherently unjust. With enough free software we can kick out the dirty contracts, patents, and licenses used to control us.
Of course those who identifty with Open Source can have their own set of strategies and beliefs, but the dominant culture and attitude are accurate to what I mentioned above. Open Source has always been a sister movement to the Free Software Movement in terms of ideology. It's why FOSS is such a controversial term, it would be unfair to awkwardly (FOSS only excacerbates the confusion about "Free") group these two communties together who differ in many key ways.
