The implications of this trend are palpable, particularly as it raises questions about the sustainability of the open-source model itself in its purest form.
Additionally, the landscape has been further fragmented by Automattic CEO Matt Mullenweg’s move to demand revenue shares from companies using the WordPress trademark. WP-Engine, an example, now faces an 8% net profit fee, with similar demands looming for other WordPress-related enterprises. Such financial strains threaten the cooperative spirit traditionally associated with open-source projects.
However, a study by Redmonk analyst Rachel Stevens found no notable growth advantages for companies implementing these restrictive licenses. The businesses that shifted did not demonstrate improved growth rates or significantly better market capitalization outcomes, casting doubts on the financial merit of these licensing changes. The broader impact of these changing business dynamics on open-source philosophies and practices remains a critical point of discussion within the tech community.
