The careers of many people (not just technical) who work in a business relying on the technology these days would not exist in the same way without open source

The careers of many people (not just technical) who work in a business relying on the technology these days would not exist in the same way without open source and free software (that whatever product or software you are currently to make those comments relies on). There's nothing wrong with criticism, but to give simplistic arguments (if they can be called arguments event) and say that it's "low quality" or "will not work" is just absolutely incorrect. But when it gets defended you call it "attacks the ego of many people"? That's just ridicules.
