To quote more fully:

"As someone who had paid money to remove cubelets before this was introduced ID feel somewhat ripped off." Note the emphasized (by me) "ID" or "I'd", aka "I would". This one word changes the entire case of the verb and implies empathizing with a hypothetical victim versus actually being one.

Except... can you use "id" instead of "I'd"? My language parser also rejected this as invalid token and I ended up interpreting that sentence the same way Xcelerate did.

I interpret your sentence as follows: in the "hypothetical" case that this comes to pass, then you, as someone who had paid money, would feel ripped off. When you say "would" here, I don't think that it makes your "as someone who..." clause hypothetical. The way that I'd say this is:

If I were someone who paid, then I'd feel ripped off.

Ah... good catch. Still, my question remains for someone.

i am not a native english speaker so i might have made a mistake there, but the other reply explains my point.
