Yes that is the same tweet referenced above. They accused him of multiple things such as "groping female devs", "trying to pour drinks down the throat" of a drunk girl who bit his face. He apologized for SIC "shitty, creepy" behavior, but he never explicitly apologized for groping & wasn't accused of groping anyone specifically. I don't see how any of that is inconsistent with the author saying above that he didn't grope anyone.
I was just responding to your statmeent that Noah didn’t ‘didn't directly reply’ to the groping allegations. As far as I can tell, he did, as you can see in the screenshot.
I don't use twitter and they have multiple UI for platform but AFAIK when you reply it usually says "replying to @...", which it didn't have in the screenshot or archive.
This is what tptacek was referring to when he said that he used this apology in response to groping allegations.
It's hard to tell what's going on in twitter threads though. Twitter sucks at archiving this kind of info.
