I've seen this attitude in so many different situations IRL and online. It's so refreshing to read it so clearly and fearlessly stated like that.
It's unfortunate that Medium have attracted all the seagulls (https://www.youtube.com/watch?v=p-3e0EkvIEM), because they've done so much awesome technical work on the platform, for example with editing (https://medium.com/medium-eng/why-contenteditable-is-terribl...).
How can platforms like Medium cultivate a culture that deprioritizes and devalues the types of spam content the article author is referring to?
