Hard to tell what’s really going on here from this article. Although it seems like five vulnerabilities were fixed and one remains (and google is being unusually patient about the sixth issue)

One thing I’ve always struggled with is the strategy of these white hat teams. I’m sure Google Zero spends a lot of time on Apple because Apple is an enormous company, large partner, and competitor in some spaces.

So now I wonder: does the release of vulnerabilities ever get effected by business agenda?

I assume it has to, although I’m not sure of the agenda here. In this case, iMessage is in direct competition with a Google sms protocol (although googles hasn’t gained much traction). Maybe the vuln is less impressive than saying, “there’s one more”?
