Not entirely sure, I think it’s just the way some influential people started talking and now everyone is replicating it. The origins in why people talk like this is probably partly rooted in a mix of virtually ‘yelling’ and old people writing in all caps because they can’t see the small letters.

I kinda agree with you. Very often people with strong moral convictions (a good thing, in my opinion) believe that evangelizing alone is the only ‘valid’ approach, while popularity and convenience are seen as somehow ‘dirty’. But it is impossible to ignore the reality of how much people in their everyday lives want and need convenience. And when it comes to social media, popularity is inherently important, because people want to hang out where their real life friends hang out too. So convenience and popularity are a material necessity if a cause is not to be a losing cause.
