I think that the LBC tokens will continue to exist but that the company LBRY will have to return all funds raised from sale of the LBC tokens and thus may sink them.
If they haven't decentralised the LBRY blockchain sufficiently and created a sustainable rewards structure for people running nodes then the blockchain will die without the external support the LBRY company was providing.
It may lead to a new decentralised blockchain or they may die. Time will tell.
somehow it is quite open, which level of decentralisation is needed...
The answer to that question is that the founders have to disappear (like Satoshi) or be forked out (like Hive) so that there is no one to sue. The blockchain has to be decentralised and self-sustaining prior to that happenning.
a fork would be too simple imo. There are people behind hive (basically everybody who showed up to the last hive fest). Would be pretty easy for lbry to just fork the chain and continue running it.
And on top, Ethereum (foundation) seems to get a free pass as well. Vitalik is still around...
Ethereum foundation is already bought by those powers that be

There are a lot more people behind Hive than who turned up at HiveFest. Anyone from Africa or South America couldn't get Visas to the EU. And accommodation was so expensive (because Amsterdam banned AirBnB) that most could not afford it.
