But isn't it also baity to use 'used to'. My first reaction now was that Whatsapp itself has been inserting spyware into their phone calls, but no longer is (=used to), yet after reading the (non-paywalled) article I now see that a vulnerability in their signaling protocol has been used by others (=used to) to allow remote code injection. Removing the creator of the spyware part from the title now causes the blame of the spyware to shift to Whatsapp, which is incorrect.
