They don't owe and apology to anyone. Nothing was ever promised. No one forced anyone to stay subbed. It's a ridiculous idea that they should apologize.
Let's say, however, that they did apologize. What would that do for you? Would it give back the money you spent? Would it make more content appear retroactively? No? Then it's pointless. So much importance is put on receiving an apology these days. Like that helps anything.
