First, there's no evidence to date that the vulnerability in question actually resulted in a data breach. This is distinct from there being actual, affirmative evidence supporting the idea that there was a breach. Here, I am using "vulnerability" to mean there was potential for exploitation and "breach" to mean an actual exploitation and exfiltration of data. I understand that some might opt regard this as a distinction without difference.
Second, it is not a common practice to make a loud media-friendly disclosure of every potentially-exploitable vulnerability. I've personally closed dozens of vulnerabilities, potentially exploitable vulnerabilities, in a variety of software packages for a variety of companies over the past decade. Of these, exactly one turned into a public notification of any sort. Hosted service companies in particular are unlikely to create what they would view as an undue media circus around bugs they find and fix internally.
With these items in mind, I submit that some people might find it reasonable that the phrasing of the article and the factual claims it makes might be at the very least unfair and potentially possessed of an opportunity to come into greater alignment with evidence-based reality.
