My problem with the ending

Them being a digital clone this whole time kinda ruind lots of stuff for me, like what's the whole point of them trying to escap or having backstories and memories they never actually experinced, it doesnt make any sence to me, in the slightest, and also jax abstracting?

What is he mad about giving the fact he is not real just a digital clone, i loved the show just hated the ending
