I think this is the important takeaway for founders and product owners. People will eventually take "just works" for granted. If you make that your value prop (and you should) it is critical to continuously invest in ensuring your product always "just works". It doesn't matter if the alternatives don't. Your users will eventually turn on you.
I think it's an important take away for product owners - if people chose your product because it 'just works', they aren't going to be happy when you change it so it doesn't 'just work' -- i.e. introducing reliability bugs, changing useful features, etc.
They may not leave immediately, but at some point a competitor will come up with a 'just work', and it will be very hard to get them back.
