I can understand about the concerns of authors.
As a reader of development topics, medium was useless for me. Sites like dev.to, freecodecamp and hashnode provide development concentrated articles. So it will be a plus point.
For authors, freecodecamp is moving articles to their site with added advantage of more visibility which medium cannot provide under its other craps.
I hate medium for its crap and stopped using it also because of its integration with Facebook.
Finally now that they have decided, they will hopefully take some time to listen to authors' problems and figure out a solution. So need to be patient.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
