Facebook, Twitter, LinkedIn, and Medium all have custom styling specific to that platform. The person you're arguing with has interpreted me exactly correctly, you're the one misinterpreting. Please don't engage in pointless flame wars based on poor reading comprehension.
The adjacent thread was not about how to interpret your comment.
It’s completely besides the point that these platforms have custom styling with regards to the web in general. The point is that people are publishing enormous amounts of content on these platforms despite not having the ability to control what that content styled like. Ergo, lack of styling is not a deal breaker for people to publish stuff on a platform.
