Hacker One will make it very difficult to keep holes open in future firmware. It only takes one set of lips to detail a hole for it to be patched and removed, regardless of how much you may know of a lower firmware's vulnerabilities. Holes have to be found and understood by a wider group ahead of Hacker One submissions to be useful and a lot of holes will become a revolving door that will be difficult to keep track of and to keep track of vulnerable FWs.
