This is a similar argument to asking if guns are bad. There's no truly evil tool/platform in the world, only the bad people who misuse it and cause harm with it. The gun isn't a bad thing until someone uses it to take another life, just like how social media is purely meant for engaging with people who aren't physically close by from you until people abuse it. When they stop meeting others simply because they're lazy and rather talk on social media, bully others, and negatively change their way of life to suit the social media platform, then it becomes bad.
