It’s called Diversity Plug and it’s a free Chrome extension that allows you “to view diversity statistics as you cruise around the Internet. If the data isn’t available, tweet companies to join the share to care initiative to publicly disclose their diversity data,” according to their website.
So, I gather that the idea is this extension will help woke white ladies shopping on Target.com to shop there anyway, but feel guilty while they do.
Also, if companies don’t have that data publicly available, with just a click of a button you can harass them on Twitter with a pre-written tweet.
