I heard Monero can help against blockchain analysis (though less so if you buy from adversaries). Unfortunately it looks like blockchain analysis was not the attack vector here, but rather buying gift cards through an incompetent intermediary.
Not really an "incompetent intermediary", Bitrefill, the company used for buying gift cards with Bitcoin received legal requests to identify the user. Bitrefill doesn't proclaim insane privacy protections, they are based out of Sweden but aren't immune to being requested to provide the information.
Monero could of helped, although its not easy to transfer BTC to Monero without P2P trades, as effectively every exchange requires KYC. Those source and destination wallet addresses are tainted, you wouldn't be able to deposit on any mainstream exchange and if they do, its for a honey pot purpose.
