Bitwarden is a password manager? And their engineer is asking, after being told a hint of serious security issues in their framework, to just forget about it and let them publish? That's an interesting approach.
It is strange. On the other hand there's something suspicious here. Some things clearly aren't being communicated properly.
"We banned any package containing Angular 1.x. We received a security report. One that we were asked not to share with you, one that we didn't even mention, we just went ahead and implemented the ban, didn't tell anybody."
