But I guess a centralized database can be edited by an insider when it comes to blockchain it can't be which maybe the key difference why they are going to implement blockchain for tracking their products but I don't really think they can stop counterfeit bottle by using this kind of track because consumer maynot be validating the products which they bought from a store with the publicly available ledger.
Inside jobs are probably barely a problem in this scenario, plus blockchain might not be immune from it if it's made to be editable, like it often happens with all these corporate blockchains.
The biggest problem is that this setup if full of centralized intermediaries - various validators, verified vendors, shipping companies and so on. In the end of the day, you trust that none of these entities have swapped the legit items with fake ones, or that they haven't tampered with in some other way. This is exactly what we have now with the centralized approach.
