I like that it's easy for me as an individual user or even small team of users who are not technical experts but still want security issues fixed quickly at no cost! It also helps us understand what our customers need so we can improve how fast they get their fixes out there (and therefore help keep people safe).
The only downside would be if you're looking into finding bugs faster than your competitors - this may slow down some bug reporting processes/workflows because time will pass quicker between when someone reports something until its actually patched by ygosooshas engineers / QA teams etc.. This could potentially cause delays with getting things released sooner rather then later which isn't ideal from my point-of view since i'm trying make sure everyone gets patches ASAP regardless where those exploits come through :) We've been able solve many different types problems ranging form simple ones such as cross site scripting attacks all way up more complex SQL injection flaws using yogosa tools & services.
