Not by you. You didn't see the benefit, so you didn't buy into it. This is fine.
The aim of a successful sales transaction is that both parties come away happy with the result. In the case of an exclusive offer one generally pays more in exchange for exclusivity. Those unwilling or unable to pay don't get the exclusive content. This is straightforward.
The wording of many exclusivity deals have a time limit. ED itself was 'exclusive' to the Xbox console platform for (IIRC) a year. Then once the exclusivity period ended it was released on the PS4. There is no time limit on the exclusivity deal for the CIV, indeed the word 'forever' was specifically used in an unambiguous way. Arguably the PS4 community may be able to overcome this, but only because the Xbox community also did.
So consider why the Xbox crowd got theirs, and try tackling your own request from that angle, because it has worked before.
