Turns out it's mostly PR and buying yourself credibility at this point.
Like, when you see someone who's an amazing software engineer with a great salary, and you know they spend a lot of time doing research. Then you suppose the research must be paying off. Over time, survival tends to equal truth.
Sounds like censorship to me: hire the people in the field who might publish research you disagree with, then pressure them from a position of power.
Same thing here. The researchers' jobs aren't to publically deface Google, they're to help direct Google down the right path.
I'm not seeing where I confuse "the ideas with their presentation" or where anyone talked about researchers "publicly defacing Google". The Reuters article is talking about ML and AI researchers who are now (recently) finding their research subject to a new review policy, above and beyond the typical peer review that they expected.
It's a bit different from the right path
Here is my steelman position: I think the objection is that the old internal review was reasonable, and while the argument can be made that the new one does not seem unreasonable to many people under the principle of "don't bite the hand that feeds you", it's reasonableness in a faux-academic setting is at least debatable, and in any case it is inarguable that the new one is more restrictive than the one that was in place when these researchers were hired.
So, at the very least, this seems like a unilateral bait-and-switch on Google's part. The company is now reneging on the representations made to prospective employees regarding their academic freedom.

Of course they never really said it for simple legal reasons, when you sign the employment contract you actually agree to a lot of censorship.
