Hm I think the spam guard ate my last comment so I’ll repeat:
I don’t think the SH are really up to converting an unwilling humanity despite all their superiority they are fundamentally unwilling to be inconvenienced so humans only have to successfully argue their case by pointing out the probable mass suicides depicted in the alternate ending and that SH society might take some casualties, since they are almost completely risk averse even the possibility of losing a single ship might be enough to scare them off.
It’s a bit like the world being unwilling to intervene in North Korea despite the overwhelming advantage, it’s just not worth a single life lost to us.
Given the SH’s willingness to self modify it would be easier to convince them to ratchet down their empathy for us to tolerable levels
Bugger there’s my original comment after all. Whoops.
