Their excuse is monnney. Look at Twitter, people are pulling their ads because they are not happy with what’s happening there. Keep the people who give you money happy and everything is fine. No matter if you would have to sell your soul (like Disney in China, to not get banned and miss millions of subscribers). Since the ad companies usually are big corporate, you can imagine what reddit their stance is.

They must have some data that this time some thing is awakening against the corporate greed.
