I believe you. Medium is the message is a term from media theory. It refers to the idea that messages aren't in a vacuum, but are shaped by where they are transmitted. Often that shape is a function of what the audience will find appealing. You can tie this sort of thing to bellman equations to get a mathematical grip on the effect.

It does exist. It can be as harmful as you think it is. Yet it isn't harmful everywhere - isn't the world at large without any variation. It is intimately tied to the environment you are in, because that environment produces the rewards. Different environment, different reward, different impact on your writing. The effect is local, not global.

Which means you get to have a superpower.

When you have a bad transformation that degrades thinking that makes the term "medium is the message" feel dangerous. So you get things like Neil Postman's Amusing Ourselves to Death. I think your post is an example of the same type of fear. This focus - on the examples of times where things are negative - it misses the opportunity. Since messages are a function not of raw ideas, but of their audiences you have an incredible power. Choose the right audience. Set the expectation for evaluation in advance. Pick the medium that helps you to think clearly and makes it easy to be judged. Now, instead of being destroyed by your incentive environment, you get empowered by it.

Take a look at Amazon's writing culture for an example of that. Or more broadly, the many companies which chose to ban powerpoint for reasons which are fundamentally related to what I'm talking about. We're not worse at understanding writing than ever before. We're more advanced than ever before, because we stand atop the giants that came before us. Yet at the same time - we're not, because that too is local and not global. The future is often already here, but isn't evenly distributed.
