If you sold FCP back to Apple with the computer, it’s all fine. Problem is - Apple gives laptop with licensed FCP to computer dealer to sell, dealer puts up price for “MBP+FCP”, then Apple remotely wipes it claiming it was there by mistake. At the very least a large misstep for Apple, and misrepresentation on the dealer’s part. Customer who buys it did nothing wrong.
The next owner doesn't get final cut pro just because you purchased it
