It is however contradicts what we know about Shadow (the guy hates shadow energy even more than Marcus do).

I'm probably grasping at straws, but it's possible too that these Defenders are powered by Moira, since the the shadow energy source existed as long as she is in the island - they may got deactivated once Moira leaving. The appearance of shadow energy due to Moira, may or may not be something Shadow did; since Moira was infected with Scourge, the source may even came from that shadow disease.

And this is totally my headcanon: I don't see shadow energy in the majority of things in Act 7. Whether it's gears, locations, or creatures. They are robotic and flashy, technologically advanced like in those sci-fi stories, and that's it. The tech may came from the citizens (Cypher being one of them, and whoever run the shop if that counts), but none of them involving shadow energy. The only trace of shadow energy we had seen was from Shadow, Scavengers (notice that they bring small capsules filled with black liquid), Titan's bodyguards, and May. And none of it came from anything but Titan. Even Titan himself didn't use shadow energy.

Involving shadow energy in the tech maybe something the Heralds ancestors did - they probably know Shadow personally (and vice versa), and they created these tech without his permission. But even they're pale in comparison to Defenders.
