I think they cannot be trusted in the long term. Even when they start out without ulterior motives, as the company evolves over the years, the ulterior motives start to creep in - Slowly and predictably, the tech becomes proprietary again. Vendor lock-in is in Microsoft's DNA. They know how to add lock-in slowly and quietly over many years. That's a big part of why I'm saying away from Microsoft-controlled language ecosystems like TypeScript. I can see Microsoft tightening its grip; how they achieve lock-in and shift towards proprietary is so subtle, most people don't see it coming until it's too late. I don't know if even the Microsoft employees who are implementing the changes see it coming; it seems to be subconscious; second nature to them.
