I'm of the opinion that #threads should not be engaged with in any way.

Not because I think it's a threat to the #fediverse, although it could potentially be.
Not because I think it will bring a huge amount of bad actors that will harass users on other instances, although that is definitely a risk.

My reason is simpler; #Facebook has done so much evil, society eroding shit, that I don't work with them on principle.

And Facebook knows that as well, which is why threads is instagram branded.
