I think it’s for “smart” washing machines that you can control from your phone etc. So that’s likely what the “updates” would be related too…why you’d need to control your washing machine from afar is beyond me but some people love smart gadgets and will by anything that connects to their phone.
There are also a lot of kits that include most of what you’ll need (especially for cross stitch). It can be a really convenient way to start and most kits come with really good instructions on how to cross stitch too.
