If what people do on their own time doesn’t affect job performance, what’s the point of filtering by random criteria? Almost like disqualify based on a hobby or political/religious views.
Social media is just like another skill. You can use it to your advantage or abuse it.
The counter argument being, they arent filtering by people who dont use social media, as much as conducting a social experiment asking people TO quit social media if they are hired. I think its well within their right to build a culture of people with a mindset, and filter for people who live the message they are trying to propagate and/or are willing to forego "social media" as a participant in an exercise.

I would also expect that a company that does "email campaigns with high conversions achieved through dynamic content such as images" would benefit from having people who at least understand social media which I assume is a large part of their user base.
Speaking for myself only, also noticed my levels of empathy towards others are also directly related to how much time I spend online and how much and what[1] I consume (and whatever headline has riled me up).
[1] It's easy to say "just avoid toxic content" when the majority of content (on social media is toxic).
