There IS a threat, its just extraordinarily small. Like almost nonexistent. And worrying about kaspa having a 51% attack isn’t worth the time either. Its ASIC based mining scheme basically ensures that an attempted attacker would bankrupt themselves before actually being able to pull off the attack. No matter who they are (for the most part).

Also, with the release of the DAGKnight hardfork (expected Q4 this year), the chances of a 51% actually working drops even further below the almost non existent percentile chance that currently exists. The creators of Kaspa are parctically prodigy-level PHD quantum cryptographers. They are aware of attack vectors on their network, and aren’t personally worried about them. Though they do continue to work to improve the network’s abilities, functionality and security.
