Nike / Pregnancy controversy - curious about climbing sponsors

the coverage of Nike's pregnancy policies for their female running athletes doesn't look good. reading that article made me wonder about climbing sponsors and the female athletes they endorse. would it be naive to believe that Lynn Hill, Beth Rodden, and the many other sponsored female climbers out there who've had kids didn't face a similar situation as Allyson Felix and her co-runners, with their sponsor Nike? I guess I am curious how "we" (the climbing community) fare compared to a more mainstream sport such as track & field.
