Maybe not an ass, that's too strong, but it's a common online pattern where someone transforms your point into an entirely different meaning and then disagrees with that transformation. It's annoying.
I'm complaining about thinly veiled ad copy wearing the mask of shared technical notes. This is seen as a bad faith effort by the publisher of such notes and a dirty trick played on the reader. Advertising should announce itself for what it is.
I'm very clearly making a distinction, I like A, I don't like B.
You're taking that, saying I must actually hate both A and B, and by the way C through Z because nobody is 111% pure of heart and everybody must have at least some motivation for doing something and nobody is entirely altruistic.... which is just this crazy extreme that it's clear I don't believe at all.
I like the incentive structure that leads Netflix to produce objectively high quality articles sharing with the community in a way that really seems to be entirely untainted by the motivation.
Ad copy in tech notes does seem to taint the motivation and quality of them, it can be innocent but it doesn't seem like it and is generally irritating to a lot of people.
Dislike of a certain kind of advertising doesn't mean I'm sitting around miserable because nobody is truly altruistic as you suggest, and that the issue. My lines of thinking aren't taken to a silly extreme. A lot of disagreements these days are people reinterpreting their opposition as exclusively extremist and that's a problem.
