Maybe make it clear you are being sarcastic here. English is not my native language, and my initial interpretation was that "they" in your post referred to the "business grade closed source stuff", and that OpenWRT is really a dangerous bet because they are guilty of all the things you listed.
The sarcasm was abundantly clear in the first bullet point.
Did you read the article? OP was very clear that OpenWRT fixed the issue in under 3 hours.
To be fair, that initial confusion is the intended effect of OP's humor. Poe's law and all, but you did figure it out so the joke seems effective. Prefixing or suffixing with sarcasm warnings neuters the joke.
