The story seems to be from a marketing-focused website, so it makes sense that the author is addressing advertisers, and how the events with Reddit will affect them.
Also, surely this story proves that the protests absolutely have had an effect. It's causing advertisers to think twice about spending money with Reddit. And as stated in this TechCrunch article, fewer advertisers are visiting the ad-buying part of Reddit's site.
So, the people who complained that these protests are pointless, that they won't change anything, have been proven wrong. The protests are effective. So if people want change in this situation then they should continue with MORE protests. My protest is that I'm not using Reddit.
I would have thought that most people who didn't want to use Reddit anymore have probably already stopped using it.
But yes I hope to see more bad news for Reddit such as this diminished valuation.
