“People on Reddit want to be anonymous, and at some point these brands want to have a real relationship with their customers"
I find it hard to take an article seriously when it includes quotes like this in a non-critical context. Advertisement is about bullshit, not about "relationships with customers". The job of advertisers is to trick you into think you need whatever they are being paid to sell. They and the companies they work only care about their customers in regards to how much money they can wring out of them.
And the parallel is that advertisers don't give a shit about Reddit as well. They are just looking for a way to maximize their ability to wring every cent out of Reddit's userbase regardless of whether the advertising completely destroyed the community.
