Because you can't have it be the wild west as that can be bad for consumers sometimes. So the law actually granted the FDA 3 years to do it. Biden could have made his "statement" on Day 1 of his presidency if he felt like it. My guess is his timing is actually the right choice here as his team felt that everything was ready and in place. I dont give Trump any more credit here than Biden. I don't like either and would begrudgingly vote for Biden on a 2 person ballot. But I don't think this is something that's political. Technology is better and quite honestly the science is better that not enough people with mild to moderate hearing loss were using the old system so this is better even if people don't get as good a fit and usage but atleast will have them in higher numbers
