There are no differences between both versions. If there were, I would.

Medium doesn't allow writers to write different versions of an article for each type of viewer.

Hence, every reader, including the ones with memberships suffer through the advertisements while the free readers gain the advantage.

Even if there was a different version, there are websites pirating articles. The creators can only be compensated through your memberships, which we're thankful for.

Otherwise, most of my customers are those free readers.
