Disclaimer: I hold Bitcoin Cash and Bitcoin Core, don't plan on selling either anytime soon, don't care who "wins".

The article notes this attack is also possible on Bitcoin Cash and other Bitcoin derived currencies. The miner attack is limited by the 1mb block size and would leave only "beefy" servers capable of withstanding it, so wouldn't BCH's 8mb block size make this significantly deadlier?

The more likely attack they mentioned seems to be more agnostic in that it relies on millions of dollars in transaction fees, but again Bitcoin Cash's low fees seem to make this an easier chain to attack. It should also be noted that a Bitcoin Core developer, as mentioned in the article, has put forth a performance upgrade that inadvertently eliminates this attack vector. So again, this seems like Bitcoin Cash is more susceptible, unless there's something I'm missing here?

It sounds like everyone else here thinks this is only bad for Bitcoin Core. Can someone please explain? Seems like this is a threat to all crypto's, in fact I'd say the existence of such attacks makes it almost improbable to believe that governments, with infinitely larger and more powerful resources, don't already have a thousand different attack plans ready in case they need to shut down crypto.
