I can't read the article, but I'm willing to bet that it's focusing on a small subset of loud opionated Googlers and convienently ignoring the 99% of employees who don't care about politics as long as they're getting paid.
Seattle/Kirkland tends to be older, more domestically settled people hired from Microsoft/sometimes Amazon, so just demographically it’s no surprise that they don’t agitate as loudly for social justice.
There is debate from other places of course, but 99% of people just get on with their job and leave the arguments up to those in MTV who give a shit. MTV can be very blinkered - rightly or wrongly the people there forget that people outside of SV - let alone outside of the USA - exist.
