Yes it does. And if/when a large enough player finds it in their interest to mount such an attack, they might very well do it. See https://www.crypto51.app/ for a (somewhat outdated) price chart.

Remember the first law of cryptocurrency though: "in case of emergency, betray your core principles."

In the event of such an attack, the rest of the system (miners, developers) may be able to simply declare the "evil" side of the fork "untrue" and hardcode the other fork as true. The fact that this is exactly opposite to Bitcoin's stated goals is no problem at all. See e.g. Ethereum's response to the "DOA Attack" as an example.
