I've bought a lot of Hewlett Packard products over the years and, because of this, have registered a lot of hardware with them. This is something I typically do to ensure I stay on top of recalls, better drivers, and firmware updates for the various devices that might need them. Although the last HP item I had registered was four years ago, I received perhaps two email notifications about updates over the span of eight years. That said, it's been very different since February.
It seems that HP has wanted to keep me appraised of every update for every piece of hardware they've made since the dawn of time ... none of which I've purchased. There have been updates for powerful workstations, RAID cards, graphics cards, notebooks only sold in the UK, scanners, printers galore, and even monitors. No PDAs, though. Nothing running WebOS, either. Just the stuff that I have zero interest in purchasing.
Alas, the company has become less relevant to me over the years1, so there's really no need to go through the hassle of trying to unsubscribe. Blocking messages such as this can be done with less than 3 clicks. Bye bye, HP.
