Now to answer your criticisms: I did not flesh out those areas you cited because I was mindful of the length of the article. I did not want it to become too long but, regardless, here are your answers >
+ "experimenting with features and pricing": I kept creating different pricing plans, changing prices and moving features between these plans.
+ "it disrupted our business": That is all I was told. They pointed to the multiple price changes but nothing more.
+ "I gleaned invaluable lessons on how to manage clients": This one should be obvious to be honest,,, unless you did not read the article.
These details might make it to the article eventually because I heard that Medium has a certain awesome feature which allows you to edit articles even after publishing.
