Beware these open source lock-in schemes
InfoWorld - Simon Phipps - Some vendors want you to think you're benefiting from open source when you're not. Keep an eye out for potential traps.
When the Open Source Initiative (OSI) was formed in 1998, one of the important objectives of those involved was to create a phrase that can be used to represent all the values of software freedom easily in everyday speech. The phrase "open source" was intended to become a strong, respected brand representing the values of software developers across the software freedom communities. The OSI website says:
Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in.
