My Opinion
I’ve been a bit confused why I see videos with that gesture censored, I feel like that rarely happened in the media I consumed a decade ago. However, I believe this “phenomenon” is older than TikTok and its weird censorship.
I’d place giving the finger at a high 2, low 3 on offensiveness, definitely nowhere near gesticulated sexual acts. You can give a child shit for using it, but the occasional finger is something I’d expect from even a teenager.
In the context of ad-supported algorithmic social media, offensive is the wrong question. It’s about brand damage.
Showing an ad next to something that actually offends people can damage a brand, but even something a little edgy might turn off customers of a brand with a more formal or conservative audience. The algorithm’s ultimate goal is to get people to watch ads, so something a little edgy might reduce the reach of that content. Censoring it prevents the algorithmic downrank.
