Third Room isn’t remotely trying to be decentralised Second Life. It’s trying to be a blank canvas for building interoperable spatial apps - that could be something like Figma, or 3D Figma, or visualising 3D data, or anything. The Tech Preview just does the typical Second Life / Hubs style social hangout experience, but the intention is to be a generic building standards-based building block for secure decentralised spatial collaboration.
