MetaMask on why they're funding Spritely's Guile -> WASM effort and supporting Spritely in general, in their own words: https://metamask.io/news/developers/meta-mask-grants-dao-funds-spritely-foundation/
> Spritely is a new model for the internet that aims to be both secure and collaborative, and is focused on secure social networking.
>
> Since Spritely applications do not require financial buy-in the way blockchains do, it’s much friendlier to new user adoption, while still allowing a type of permissionless application to be built where it’s rooted in a user’s own sense of trust and safety. Their capability-security approach to permissionless computing makes a lot of sense to us at MetaMask, and we think tools like it can enable exciting kinds of applications.
