chain that the US government allows to still be called "Bitcoin" without being prosecuted for trademark violations.
It's funny how delusional some people are

So which chain will you choose and which chain will you sell your duplicate coins on?
Isn't it obvious? A malicious fork that only has 2% support is not something to even think about. It may not even come to existence.
2% support is a joke. They must have more than 2% support to shift support away from bitcoin. If the fork comes to existence how can I extract the new coins from my wallet? Which name is the latest fork called. I will dump them if I can extract them. Which exchanges are recommended to dump the malicious coins?
Like most shitforks, they will most probably try to call themselves "bitcoin" as well. Similar to what bcash guys did in early days back in 2017 like having it listed as bitcoin on bitcoin.com website (Roger Ver owned the site).
I don't think this chain would come to existence considering it only has ~2% support from miners but hypothetically the process to claim the "airdrop"! is similar to the past ones. Read the LoyceV topic (the link is in the comment above mine).
The biggest problem is that since this is an exact copy of bitcoin (blockchain and code) the risk is the lack of what's known as "Replay Protection". That means if you create a bitcoin transaction and send it out (on bitcoin network), the same exact transaction is valid on this forked chain and vice versa.
So if for example you find an exchange that sells this shitforkcoin and send your shitforkcoins to an address generated on that exchange (on the shitfork network), your bitcoins could also be sent to the same address (on bitcoin network) as well; and getting them back from the exchange could be a problem if the exchange doesn't want to cooperate which they usually don't.
That makes dumping such forkcoins complex. You first need to generate 2 addresses that you control and then simultaneously send the same coins on both chains to different addresses on each chain (eg. bitcoin to address_1 and shitfork to address_2). If that failed due to replay attacks, you should repeat that until you succeed in separating your coins. Then you spend your shitforkcoins from address_2 to the exchange.
The other difficulty you'll face is the slowness since as I said this malicious fork doesn't have any support and with low hashrate blocks could only be found at very large intervals which makes confirmation a nightmare not to mention such a chain would be susceptible to 51% attacks.
