Yes, it is. It's specifically called concern trolling: https://en.wiktionary.org/wiki/concern_troll
In this case it's because the mass-market operating systems with which QNX could compete already do the things you're “concerned” about. QNX could only be an improvement in that regard.
As someone who has not worked in automotive QNX is a totally unknown brand and based on the linked website I had trouble finding out what it actually is. Also the wikipedia source just stated RIM and might not have been updated at all. Also RIM/Blackberry is not a brand that is positively recognized.
With something like Ubuntu it was an easy, verifiable story who is behind it and what they are doing. That's what the linkd QNX page was missing, and I pointed it out because I actually tried to do the due diligence and see what company is behind it and where it is located.
