Forward looking statements can come from anyone and become sticky when considering security laws. Imagine everyone at Apple was sharing their full triage and timeline for every issue; one can then make informed decisions about their stock price, and investors could sue if those statements turned out to be misleading. At a certain point, the risk is too great.
Ok, but even if that were true , it costs nothing to say "we'll let you know when we think we have fixed the issue so you can then retest"
"Idk lol, it'll probably be fixed one day, keep testing and find out" is a pretty crappy response.
