I’ve already shared your question with the team because it feels more like a product and vision question rather than a developer one.
Currently, both the OISY frontend and backend are controlled by the foundation, but they are now deployed using Orbit, which means a few selected members of the foundation must approve any deployment.
There is also a proposal to hand over a signer canister to the NNS (see post). The signer, for example, is used to derive the ETH address from the user’s principal.
This is the current status to my knowledge, and I’m not aware of the plans for the future. That’s a question for the foundation.
