The tweet discusses perceptions in the penetration testing and bug hunting community regarding Web Application Firewalls (WAFs). It references an engineer named Orwa and the early days of penetration testing when WAFs started becoming popular. Many people, especially beginners, believed that with WAFs in place, finding vulnerabilities would become impossible or much more difficult, leading some to leave the field. However, over time, many techniques to bypass WAFs have been discovered and continue to evolve. The tweet suggests that this cycle is repeating itself, implying that despite the challenges posed by WAFs, bypass methods are continually emerging and keeping penetration testing and bug hunting alive and dynamic.
