I'm just trying to understand, which "large-scale" companies can use the technology, which is held by group of anonymous developers. I think its kinda big risc.
Talking about bitcoin - yeah, it was created by the anonymous developer(s). But he created it and left it, gave this technology(done thing) to the humanity, not continuing to develop it from the shadows... this is my point of view

I don't get why this a no go for someone ( talking about anonymity ) . The technology will not be held by the team , it will be distributed across a network that will get paid for the work commited . And the technology itself is the important part here , not the identities of the dev team . When you go buy a car for example , are you buying based on the person who manufactures it or by the performance , service , credibility etc ?
If SN continued to develop BTC "from the shadows" what would be the difference ? Do you think that it could kill or harm BTC in such case ? I don't see any point here , maybe you can elaborate ?
