Funny, it never occurred to me that you'd get to continue vesting while not working (I have no idea the policies at my current or former employers).

I get that people respond emotionally to these things and just go with "Amazon bad, mothers good", but this policy just seems... obvious?

If it cancelled or reset to zero that would seem harsh and not in line with norms, but a policy of "you vest for each month you work" feels perfectly fair and reasonable to all employees.

I can see your point, however if vesting is a form of compensation, it seems reasonable that this form of compensation would continue with other forms such as healthcare insurance and salary.

How about promotions? Would you expect to be promoted up the corporate ladder while on extended leave?

The whole point of paid parental leave is that employees continue receiving a salary (and health insurance, 401k matching, etc). Logically one would expect that stock grants would vest during this time period too. Anything else unfairly penalizes new parents.
