As bad a taste as it might leave, I'm not sure there's a leg to stand on here. You can still use the product you bought in the form you bought it (as I understand it), under the license you bought it, and you'll still get access to "lifetime updates" included. Granted, there might not be any futures updates to be eligible for as part of that, but unless you had an SLA on a roadmap, seems likely there's no real recourse here? Business-wise, having a sale on something you're going to deprioritise/eventually sunset passes my smell-check, though there's a slight whiff with the leading point around "lifetime" (given that the lifetime seems to be, ahem, pretty short...).
