Four reasons to pay extra for open source software: 1) Open source software provides greater freedom and flexibility through the ability to use, study, modify, and distribute the software. 2) Paying for open source software subscriptions provides value through services like support, maintenance, and ensuring the software continues to work and deliver needed functions. 3) Proprietary software licensing requires expensive license compliance management, while open source licenses have no user limitations or compliance requirements for non-commercial use. 4) Open source software allows for simpler, more flexible ecosystems where employees, partners, customers and citizens can all use the same software.
