I've never seen ads on my Medium articles. Medium's PP is available to those in countries where they are eligible and can join from the start by becoming a Medium member.
Second, Medium does not own the content, the writer does! You can post it anywhere you like or take your content off the platform as well.
In fact, you can monetize your content even on Medium outside the PP by adding affiliate links or links to products you may sell.
I think you need to clarify these, since these 2 points are highly misleading to say the least.
