I don't find the arguments convincing, as someone who loves OpenBSD. There's nothing that jumps out to me that say "oh yeah, that's a great idea to switch away from Linux". Many of the negative quotes about Linux, even from Linus himself, were 5+ years old when the post was written (2020).
Really, the article is about why you should adopt open source software over "corporate source" software. Viewed in that light, it makes sense that large corporations tend to prefer "corporate source" software, whereas smaller organizations and hobbyists should lean toward open source software.
