That's because these standardization bodies are run by the same companies benefiting from them and are incentivized to serve their owners and not the public domain. The goal of these standards is not to be open and free but to allow for multiple proprietary but compatible implementations to exist. For better or for worse, mobile phones need to be able to talk to each other via standardized infrastructure and you need to agree some technical specifications for that. That's the need these standardization bodies serve. Making it easy for others to enter the market is not a goal and actually explicitly not a goal. Implementing these specifications requires access to patents from the main specification authors. This ensures these make a nice profit and ensures companies are willing, and even eager, to commit their IP to being part of a standard. It's the key way for them to monetize their R&D.
