Hmmmm. Apple does not 'select' those. Apple designs and manufactures those processors. Why would they not be responsible for issues? Who else should be sued in this case? Intel is already sued for Intel processors. Now Apple is sued for their own Apple processors. Seems in line with expectations.
So why haven't we seen countless lawsuits in the past for the security exploits found in Windows (for example)? How many people over the years have had their computers hijacked by a virus or malware? Why aren't they filing to hold Microsoft responsible?
The answer is simple. Because they don't have a case. It's literally impossible to produce software that's 100% bug free. There will always be exploits discovered (esp in something as complex as an OS). All someone like Microsoft can do is take the necessary steps to make their software as secure as possible when the design it, and when exploits arrive to patch them as soon as possible.
The same thing applies to this processor bug. Apple, Intel and others didn't intentionally design the flaw. They were looking at making the fastest processors possible, and someone found an exploit with their method. Now that exploit is being patched. This is all that can reasonably be expected of them to do. You can't protect against every possible vulnerability in hardware/software. To imply that Apple or Intel should be held to such a ridiculous standard is beyond asinine.
