Reading the article I think most people don’t need to worry about upgrading because of this flaw; this would be a very targeted attack. And I can understand not letting the firmware upgrade; I’m pretty sure I’ve seen examples of nation-state hacks for phones that involve attackers installing an “upgraded firmware” that disables security protections to access otherwise secured info. But yeah, cost is definitely a risk with this design.
I counted backwards once and figured out I was conceived the same month as my parents’ anniversary. I thought I might’ve been the result of their anniversary trip to Jamaica, and for some reason that made me uncomfortable knowing that. A few years later they were talking about the trip and that they didn’t know my mom was pregnant at the time. So thinking more it made sense that I was actually probably from a week or two beforehand, but then that means mom was drinking while pregnant because she didn’t know (although I’m assuming that early doesn’t have much impact).
