After reading this thread I'd say you have certainly done Due Diligence!
And if you read the patents that are cited in your link, they will say what was wrong with all the previous products that tried to address this problem.
I guess the safety of various fixes and products can be judged by the number of lawsuits, at least in the litigious U.S.
Problem is, any product or company that's been around long enough will eventually get sued, so what is the 'base rate'?
There was a fuss about a Tesla vehicle catching fire but it turns out that 1 fire per year per 800 vehicles in the U.S. is 'normal' (the base rate) so with 25,000 Teslas on the road they could have ~30 fires per year and still be 'OK'.
And it was just this kind of ratio and proportion reasoning that got me illegally forced out of my guv job; they thought I was a whistleblower. And I guess I am!
