"the advertising giant has terminated 48 of its 85,000 employees for harassment"
That is an absolutely meaningless comparison, 85k employees are not capable of harassment. If the quote had been about terminating 48 out of 100 sexual-harassment-accused employees, then it would be meaningful.
It would also be admitting that Google had 100 employees (managers) accused of sexual harassment, which would inevitably open Google to a tsunami of bad press. Whether 48 terminations is a good result or not actually cannot be judged without knowing the specifics of all the accusations (being accused doesn't mean you're guilty, in an ideal world).
So yeah, Google isn't about to admit how many cases it has actually handled (much less how many cases it has ignored), but even so, comparing the number of terminations to the number of managers would have, apparently, been a little bit closer to the mark.
