This is not planned obsolence, Jim. This is an exploit of how CPUs prefetch data and their speculative execution, basically how they were created to work as fast as they do. Spectre exploit doesn't impact just Intels, this is not Intel's "masterplan scheme" or anything.
The initial fix Intel did causes random reboots on Broadwell and Haswell platforms. They have now identified the cause and will produce further fixes, which is an entirely sane thing to do, nothing wrong with that. And again, absolutely nothing to do with planned obsolence. More like increasing security. But if your computer is not online, of course you don't need to care as much.
