Daedras adopting Dwemer artifacts as their own means the Dwemer surpassed the Daedra in power, cratfmanship and godhood
Malacath uses Volendrung a Dwemer hammer who was an unique hammer you find at the last living Dwemer. It then got used by Malacath and when you give it to Martin Septim he says: „Who now knows the tale of how this Dwemer hammer came to embody the power of one of their most bitter foes?“
In Malacath opinion this must been he was so impressed with it and saw it as the ultimate weapon. Same goes for Peryite with Spell Breaker in Skyrim. It was constructed by the Deemed, and Peryite was so impressed with it he gives it to the last Dragonborn/his Champion in the events of Skyrim.
This all happened after the deamed already left Nirn leaving behind their craftsmanship in everlasting ruins that still are active. The Daedra never managed to create this sort of status among the people of Nirn. They want statues but their also desire cities, lands, even nations and races as in the case of Aura and Boethia and the Dunmer.
The dwemer outmatched all the Daedra. They are for the freaks
