Nobody is "finger pointing" Rachel for the vulnerability. They're calling her out for how she communicated it. I feel that's totally justified. For instance if someone found a critical RCE, but the report was a barely coherent stream of consciousness, it's totally fine to call the latter part out. That's not "finger pointing".

It's the developers job to respond to bug reports in the form of vaguely written blog posts?
