You must be quite sensitive to see this as “acidic”. I have seen this guy speak at several conferences and he is absolutely the opposite of “acidic”. Here’s an “acidic” comment for you: He makes great games that people love and he doesn’t owe you a thing.
But have you seen him write? I'm talking about the article and the quote above shows some very aggressive sarcasm. I believe calling it acidic is appropriate.
If I provided the same kind of reply to you it would either be downvoted to hell, flagged, or deleted by mods. Using 2 different moral standards for the same action has a name.
