It’s more GNU than Linux. With proprietary software, people are forced to compete to come up with the quickest solution rather than the most correct. Inevitably under a capitalist system, few large conglomerates dominate the field of technology and bend society to its will leading to a space where only venture capitalist grifters can thrive while the public suffers.

A monoculture is more vulnerable to being wiped out by a single disease. so in the end, like all problems caused by capitalism, will cause the whole system to collapse.

It’s not being an “evangelical” which is the lazy excuse that capitalist bootlickers give to any socialist project. It’s about being for the workers.
