Follow the links from his Wikipedia page and you can see Twitter threads where he responded directly to allegations like this with links to the apology.
Ok since you don't post links I'll assume you are referring to:
'Bradley’s statement came the morning after concept artist Betty Jiang posted accusations on Twitter about a “bald headed crusty assed ‘well known’ artist who went around groping female devs,” saying that she hoped “to never see you and your shitty v-neck shirts at any workshops or conventions.”'
He apologized for a lot of things, but I don't see him admitting to or apologizing for groping anyone.
As I said: you can see screenshots of threads where he was accused both of "groping" and of taking advantaged of intoxicated women at events, and he responded with a link to the apology. Follow the first footnote from the Wikipedia article, and then click the screenshot on the first message in the Twitter thread.
I have no way of judging the veracity of either side of this argument, but it sure looks like the allegations against him were specific --- at the time.
So the tweet paraphrased above, here is the link... Which again he didn't directly reply to and didn't say anything about groping anyone in his apology... Is it really that hard to link?
