Yeah, people who live the majority of their lives offline and mostly use the net for distractions or a means to an end have no ideology on the matter. They go to where the most people are or at least the ones that align with their target audience.

This is very common with people who make stuff to sell and use Instagram/tiktok/etc as their sole marketing platform. Moving their activity to a less active platform (or just adding it to your social account list) can effectively cost them more in time or money that makes it not worth the hassle for them.

And a lot of normal users stick around on these sites because its the only place their favorite artists/vendors/people are. Its a conundrum.
