In a bath faith manner? What's bad faith about it? Enforcing a patent you own isn't bad faith. That's the point of a patent.
Maybe it's not, but it exhibits all the qualities, so...
You can't claim to desire safety for all while preventing anyone else from increasing safety.
The Bosch system was totally different, sounds superior on several fronts, and SS were only able to stop it by dint of technicalities and plain flaws in the US patent and legal system that allows frankly absurd arguments to win, and most pointedly, SS were willing to do exactly that. Not because Bosch stole anything from them, not because Bosch were sonehow harming users by doing the SS system but not as well as official SS, not because of any justifiable reason except that they physically could.
There is no way to justify SS actions.
"The reason why he shouldn't be trusted here is because he's done things in bad faith in the past"
"What has he done in bad faith in the past"
Your assertion "He's doing so in bad faith right there".
You can't also attempt to conclude your antecedent from your consequent.
