AITA for not telling my Dad he isn't getting the inheritance he's expecting?

It's not just the anger, dude. Depending on how much longer your grandparents live without him knowing he's out, say 10 more years for instance, are you ok with seeing your dad have nothing in his old age? You know he's not saving and that's his mistake, but letting him think he's fine and continue to not save and also following your grandparents will to not give him money after they're dead means that you will have to see your dad spend his elderly years broke, unable to retire and unable to afford healthcare. You can help prevent this now by forcing your grandparents to grow some balls and talk to their son while there's still time. It's hard to imagine your dad looking old and frail right now, but I promise it will happen and it will be heartbreaking.
