p2p seed nodes point of failures in btc blockchain

Hello,
i'm discussing with some dev friends about the security of the btc blockchain, in my opinion having all the hardcoded seed nodes down or hijacked could be a possible point of failue cause all the new nodes/clients in that scenario have no idea where they are going as well as every new wallet transaction.

My friend replied to me saying that the blockchain in a similar scenario will still running on the other nodes but, having the seed nodes hijacked leading new nodes/clients on servers controlled by some organization, could lead to have the old btc server nodes unusable because no one can still reach them and the new server controlled by some organization becoming the new trusted ones ?

Reading the btc whitepaper at 5th paragraph where node workflow is explained and the weaknesses section (sybil attack) on bitcoin wiki let me think that this could be possible by a big organization like a government.

I will like to know what do you think, in the internet similar sceraio seems to be already supposed in the past but i never found technical explanations, so please if you want to respond in you comment add some sources or documentation that support you words. Thanks
