Thanks for writing. This highlighted section was my main takeaway as in it’s my responsibility to help demonstrate their expertise. As for why they think their content should be by subscription: because the articles are averaging almost 3,000 words which is a ton of effort. None of these articles would have been written if not for the money that Membership provides. That’s not a reason for you to pay, but that’s the explanation for why somebody has to. Either have paying members or don’t have these articles.
