Work on... like, some kind of kineticist upgrade book?
Keeping on that 'car' analogy, this errata's reactions are basically people getting the car back from the shop and going "WHERE THE F*** ARE MY WHEELS", getting told "woah there. they did good work, and you should be grateful they changed the oil like that"
Which leads a lot of people to immediately think "F*** OFF ASSHO*E, I WANT MY F***ING WHEELS BACK", causing others still to start thinking "why are they so damn rude to the mechanics"... And then there's the lot that still see the axles and are thinking "But aren't THOSE the wheels right there?"
And then someone else is like, "Isn't that his dad he's screaming at, who gave him the car in the first place, and did all that work on it free of charge? And all he ever pays for is gas? Man, I'd light his car on fire if I was in his place."
