You don’t need to watch them, but the possibility to post is still better for the community. The porn side of Lemmy will be a shadow of it’s former Reddit self without videos/ability to play redgifs videos in app. Then you have the dog videos, and then the TikTok videos which you might not like but it’s undeniable they draw a crowd.
Thing is, with videos, which I’m assuming will come eventually, it will be the best one for me. Most social media feeds are awful, looking at you Instagram, TikTok and Reddit default app. Far too much soggested content.
