The only problem with this is that the Threads privacy policy states that if one of their users interacts with YOU, it gives them the rights to scrape and sell your data.

Defederating from any corporate-controlled instance is how we can keep the fediverse healthy.
I this this requires some more subtlety: defederating from a corporate-controlled competitor can prevent Embrace/Extend/Extinguish.
Meanwhile, I think it would be perfectly sensible for businesses to create their own Fediverse instances on their own domain to control their social media presence, and avoid paying to be recognized as who you are. Communities on their instance could replace the once-ubiquitous forums.
I’m akeptical. I suspect they’ll mostly use control of an instance to inject their marketing and data collection efforts into the fediverse.
