Of course, they can. But don't get fragile and offended when someone asks you to back up your constant stream of 'opinion' with data on how you reached that opinion. If you can't, people are more than entitled to call you out.
And yes, nobody is more informed than anybody else when it comes to the device. That much is true. When it comes to the regulatory process, that opinion falls apart. I have tried, over several posts, to give insight into the regulatory process, but the same names totally ignore the information.
Apologies if this comes across as big-headed, but as someone who has been involved with dozens of Class II and III medical device launches and deals with the FDA on a near-weekly basis, I find it extremely grating when people ignore my posts and comments 'lol the delay means it doesn't work.'
For example, I have previously addressed every single one of
@ColinUK's points above, yet they have been ignored - then that obviously means something is wrong with the device.
