The angle is manifold. When a new hardfork is created, particularly with something as valuable as bitcoin, people research it and learn about Safenet. Owners of BTC will want to extract value from their copied accounts on the new hardfork coin so they will have to install and use Safenet. General publicity will also result from doing this that could really benefit Safenet.
A hardfork does not need to have a blockchain at all if we can maintain the all the core features of bicoin in safenet - in fact we could completely rewite bitcoin. To be clear – blockchains are not features, they are tools that enable features, like immutability and transparency. And those features can be duplicated in Safenet without a blockchain.
