I ended my Medium Subscription today.

Reason:
Non Technical =>
Repetitive posts, often by the same author saying pretty much the same thing.
Multiple copied of the same post being suggested all the time.
Click baity titles which have no real content.
Amazing amount of self promotion rather than any actual value in the article.

Technical=>
Very slow loading of media on the pages, videos don't even load.
Provided solutions in tech based articles often unconventional, super harmful in long term if you have them in your code.

I do agree that they definitely have some good content, but I don't feel it's enough to make me stay given all these issues.
I'd rather just use it on my pc without logging in.
