DHS is a law enforcement agency, which regularly uses surveillance techniques, some of which exploit security flaws in devices and software. When you share information about security flaws with DHS, you're sharing them with ICE and the Secret Service.

The FTC, in contrast, is a consumer protection agency. They don't kick down doors and they don't arrest people.
