This argument makes sense when you're talking about a problem that one or two people control rather than a large system with higher stakeholders who may not have interests aligned with your own.
But I'll assume you're right for a sec. Let's assume that Google cares a ton about making sure their privacy policy is consistent, but it's just an insanely hard job and nobody could do any better.
Why does that matter? In that scenario, I still don't trust your privacy policy. I don't care whether it's inconsistent because people are incompetent or because the problem is hard. In either case, the privacy policy is unreliable. If I can't trust it in Chrome's case, how can I trust it in Gmail's case, or in Adword's case, or in any other product?
In a way, saying it's a hard problem is even worse. I would have felt better if you had come back and said, "oh, the Chrome team is just uniquely incompetent, but everybody else has got their stuff together."
But then again, I'm neither in privacy team, nor Chrome team, know no specifics of this case and can't really argue any position (note how I'm neither defending nor condemning the issue of OP). Just pointing out generalities that I don't see mentioned.
If Google itself isn't acknowledging the problem, or worse, if Google is actively thwarting or working against its own privacy team, then anyone who gets involved will also end up starved for resources or moved to other teams. Google is not a level playing field for people who want to change the system from inside.
So it's not wrong at all for you to bring this up during an incident. But if we take the premise that this incident is the result of one of the largest companies in the world starving its own privacy team, not paying enough to attract talent, or not giving them enough input into internal processes... well, that's honestly something that needs to be discussed company wide. That's a very serious situation.
And if that's the case, users should be distrusting Google's privacy commitments until it has that conversation. The first step to fixing a problem is acknowledging the problem -- you won't get anywhere trying to fix a system that doesn't want to be fixed.
From the responses that have come out of Google regarding this incident, it doesn't sound much like it wants to be fixed. Changing that is the first step. Hiring people is the second.
By all means, let's talk about Google's privacy team. I am all for that. Let's get productive. But let's get actually productive. Let's have an open, public talk about management and resource allocation, and why the team is understaffed. From Google's AI/self-driving divisions, we know what it looks like when the company gets serious about attracting talent. And we know it has the resources to do so.
Unless you are actually offering a job at Google, it's not a reasonable train of thought, it's a (somewhat pissy) cop-out.
I give them the benefit of the doubt on their intentions (although I'm less sure about upper management). But regardless of their intentions, they need to get better at thinking ahead.
Situations like this are always a little complicated, so I don't want to oversimplify or claim that they should have been psychic. But... it really shouldn't have been hard to tell that people would be upset. I kind of feel like if nobody on the Chrome team could have predicted this, then the Chrome team is seriously out of touch with users.
I mean, heck, the change contradicted Chrome's own privacy policy, which had to be updated after the fact. Is there seriously no process to check stuff like that before features ship? How is anyone supposed to trust Google's privacy policy when any team can break it inadvertently and it takes a Twitter thread weeks later for them to find out?
The Chrome team has a nasty habit of simultaneously saying, "just trust us, we're experts, we know what we're doing", and "there was no way we could have predicted that users would be upset by this."
Both of those things can't be true.
