That community of content creators chose the platform for the benefits of discovery, SEO and convenience. While I agree that there's great content on Medium, those upsides come with a few downsites for content consumers and losing a few of them comes with the territory. It's still a net positive for creators anyway, otherwise Medium wouldn't be a thing.
if the author cares so little about their readers that they choose to distribute their content on medium, there's a good chance that content isn't worth reading.
An author may care so much about readership that they value reaching 50 million people, over a few dozens, if the price to pay is some inconvenience with the medium (see what I did there?)
One easy way to communicate to said community that Medium provides a terrible experience for readers is by reducing page visits so that they start wondering about it and look for alternatives.
