Yeah, it reads that way to me -- this post was a public leak, not just criticising one founder but also implicitly repudiating the culture and governing processes of the forum. If the forum and trust in the forum being a private space are important to the program, I think being asked to leave sounds reasonable.
I'm not saying that the internal processes were satisfactory -- I don't know either way, and I think this position is consistent with both cases. I think the two options available are,
1. Criticise publicly and leave, and
2. Work within the system, and accept outcomes that go against you.
I guess it would be important to know if anyone internally commented how jumping the queue wasn't a cool thing to do. Leadership internally needs to set good examples and question questionable behavior so folks know the boundaries of acceptable behavior.
Shooting the messenger, if the messenger went through all of the proper channels and made every effort to rectify the matter appropriately internally, would then be counterproductive because it magnifies the issue by creating a martyr.
It's difficult to know what actually transpired, but I don't think a reasonable person would air dirty laundry without trying every possible avenue and appealing to leadership to take a position. So either they're unreasonable or YC let them down, it's impossible to say without independent observers in the know stating their impression.
