Seems irrelevant, but yes, I do own Intel stock (it has more than doubled the performance of AMD's stock over 10 years, but again I fail the see the relevance of that to this conversation). I also own Intel processors and have owned processors from Apple (iPhone), Digital (DEC Alpha), AMD (Opteron), IBM (PowerPC), and I'm sure others I can't remember right now. And the funny thing is ... they all worked and probably would still today if all of the supporting hardware was still around. I'm also pretty sure that if we found a flaw (and I'm sure we could) in any of those processors, the manufacturer would tell me where I could put it if the product was more than 10 years old.
Flaws have existed in nearly every product ever released since the beginning of time, there is little expectation that anything is perfect and companies that support their products well are rewarded, but there is a limit to the amount of support people should expect or demand, in my opinion. This is not a situation unique to Intel, and AMD is nearly as culpable for the same activities, just like the performance hit they took with the Phenom when their "flaw" was patched through a BIOS modification that affected performance (https://www.anandtech.com/show/2477/2).
Intel's design was not garbage, it just swung farther toward optimizing for performance than it did for security (and they weren't alone as most chip designers did the same thing). This is a learning curve that everyone is going through and at some point we will have to decided whether we value an extra 5% performance or protection against specific forms of security threats. As a home user you may opt for the security protection, an airgapped data center may prefer the extra performance shortcuts that sacrifice some security.
We, as consumers, drove the market to this place, by constantly demanding additional performance from hardware vendors. Now we're realizing maybe we went too far and we'll see that probably scale back and be rethought as a result. But let's stop pretending that Intel has to be the scapegoat and let's stop blaming them for not supporting 10-year-old hardware when nobody else is doing that either.
