That doesn't mean it was an accident, it could just mean that they realized it's a problem. Especially as this issue was opened after this HN submission got posted.
Issue opened 3 hours ago, thread posted 2 hours ago. I look at Brave with skepticism as one should with a company that flirts with crypto, but in giving them a fair shake, it's important to keep the facts straight. That said, in keeping the facts straight, an issue opened a week ago citing this as a problem was closed in favor of the one opened by the Brave VP.
It’s a publicly viewable GitHub issue that people can still navigate to or comment on, it’s not like it was scrubbed. It’s surely a PR move to show they’re on top of it but not anything to read into in my opinion.
