No, that's not how LN works. If the other party suddenly closes the channel at an old state that is beneficial to them, the funds will get locked for 2 weeks and you will have enough time to publish a transaction with a more recent state, which will reward you with whole balance of the channel [0].

As that article explains, that only works if the non-closing node notices the problem in time to contest this. And, according to your article, this period is 24h, not 2 weeks.

I'd also note that this seems to make DoS much worse of a problem. If I have a transaction with a node that has gone offline and can't be reached, and I initiate a forced closure, what's to stop the other node from taking all the money in the channel, especially if I am not constantly online and the channel state I can't know for sure if the other node may have made some transactions while I was away?
