I will abstain from going through the market or business challenges of telecom operators and the wholesale businesses specifically, as this has been covered in the media and has been a HOT topic at conferences for years, getting worse to the point of unsustainability.
This development is not something uncommon in other markets and industries, which are or have been going through cycles of dramatic changes over the years. Some professions even simply died out. They had no voice or chance to stop evolution and their “species” entirely disappeared. Almost Darwinian!
