And yet the vast majority of the population doesn't do it, because they don't need it when they're perfectly happy with mainstream social media, which is the point.
The vast majority of the population doesn't do most individual things you could possibly name. There's a vanishingly small set of things you could name that the vast majority of people do without over-generalizing. That doesn't necessarily make them niche.
Most people work, but most people aren't a programmer/barber/chef/construction worker/farmer/etc. Most people listen to music, but most people don't actively listen to <insert any artist below top 100 or so>. Most people use some form of computer daily/weekly, but most people aren't visiting reddit every day, or HN, or a specific youtube channel. Most people aren't a small business owner, but small business owners aren't a niche thing, they are a cornerstone part of the economy.
Add all of these "not mainstream" activity participating people together, and suddenly you have most of the population.
