I don't believe that "accepting the change" in the sense that BA portrays it is a resolution of the EC 261/2004 claim for reimbursement.
It is not as though OP could decline the change and retain his seat in F.
BA is certainly free to make an offer in lieu of reimbursement, but that would only be effective if the reimbursement under the Regulation is known, e.g. "you are entitled to reimbursement of X, but we propose to offer you Y"
