This sounds like a take that you'd probably only find on HN though. It seems dubious that regular Apple users see any issues with the software stack or with Siri, certainly not to the point that it'd be a branding problem for Apple.
Next time you're speaking to a close non-techie friend or family member feel free to ask them how often/whether they ever use Siri, and then ask them why not, and you'll realise that no, this isn't some HN-specific peculiarity.
