If the change goes through despite the issue being known, that is bad, and that will be a clear sign they don't care that adblockers are getting shut out. Still won't be proof it was intended to do that, but at least there's a different level of outrage you can apply to it.
This is not about who does or doesn't deserve the benefit of the doubt. It's about not having knee-jerk reactions to headlines. In the current political climate, that should be given some serious thought.
Edit: In fact, so far the only thing this thread has achieved is having people go in the issue tracker and leave their comment. You can guess what will happen next: Outrage and abuse in the comment section, followed by a lock, because of fucking course they should lock when there's abuse. This happens every damn time there's a github issue being linked on HN.
What this behaviour does is it prevents an actual discussion from happening.
