these remarks were made back in i think like 2012. the comments were true at the time, and the criticism was valid and timely and very welcome. many of the issues he points out have since been addressed. further, these comments were made by (as you observe) the creator of linux, and were addressed to a crowd of presumably linux enthusiasts.
this is like looking at a company's internal communications document, "How can we improve our product for customer retention?" with a bunch of unflattering remarks about slapdash make-work minimum-viable-product by-committee decisions over time leading to a less-than-ideal end product, and what should be done about it.
instead of complaining (badly) about linux, i ask you just mute discussions about it you don't want to see. "foss advocates not welcome" yeah fuck people who want to use and make free software lol what a fucking chud
