Seems like you are implying that there is some hardware they could move to where they would not have the problem, were they not stuck with their current one.

This makes me very curious. What hardware could they move to that does not have the same problem?

Or “consequence”, as you call it. Though in my mind performance problems are still problems. Were they characterizing it as a cache invalidation problem? The first paragraph says “a performance problem involving caching”. I read the title as being because their false sharing problem arises from the way CPUs invalidate cache lines, to ensure coherency, which is notoriously complex.
