The article says that disabling hyper-threading is a worst case scenario, but I don't think it is.
Intel themselves said [1] "Intel is not recommending that Intel® HT be disabled, and it’s important to understand that doing so does not alone provide protection against MDS."

- jand 7y agoIf my understanding of the announced updates [1] is correct, the need to update exists for non-HT CPU, too (see C3000 series and such).
