I feel like the HN title here is misleading. You can’t delete your Threads profile, you can only delete your Instagram account and your Threads sub-account will follow.

Also this is quite clearly stated inside the Threads app: “Some settings, such as deleting your account, apply to both Threads and Instagram and can be managed on Instagram”.

Deactivating your Threads account, on the other hand, will not affect your Instagram account in any way, this warning is there in the corresponding Settings section as well.
