They saved some cost on building the UI etc. by well semi-stealing it from Twitch after a leak but that's just a saving bootstrapping cost not long term operation cost.
When it comes to general advertisement friendliness they are far worse then Twitch, i.e. where Twitch struggles to sell AD slots Kick probably wouldn't even bother.
Like many other start up like companies Kick is not currently profitable and lives from investor capital hoping to make it through.
Kick is deeply intertwined with gambling and many streamers on it frequently are in legal gray area when it comes to gambling law in the EU, they tried to somewhat get way from it but AFIK failed for now.
Kick has many streamers which are often seen as ethical problematic, like being associated with neo-Nazis, making it a no go for most advertisers. But also many streamers stay away from it for that reason and also (maybe more so) the gambling reason.
So AFIK Kick isn't likely to make it longer, except maybe as legally and ethically questionable gambling paltform.
