If they're actually smart, they would've tried to cash in on the recent youtube adblocking issues, and invest in making edge able to block youtube ads properly.
If they did, i bet their usage statistics would grow in some substantial amount. Obviously, this could open a can of worms, since they'd then be open to being sued by google...
With how they slipped back into making it more difficult to exorcise Edge from being opened for various links and file types... I think "FTC fine" might just be a line item on the business expenses....
