I share your derision for the TikTok mentality, and struggle with it a little myself; however, I do believe there's much value in the ability to reduce communications to qualitatively fewer bands, even if it's not absolutely necessary.

For example, I'm neither deaf nor blind, although my most common complaints are variations of "this podcast could have been a newsletter" and "why aren't you captioning media". I believe that even when you have nobody who requires this in your audience, that as long as your purpose for sharing the media isn't the information you get from observing reactions¹, then it is a healthy boost of communications fidelity to include some textual caption, whether simply repeating the media message like captions, or providing further context and interpretation.
