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.
If the company is maintaining all the nodes in a closed space then there is no point of doing this, but I feel they are trying to do implement blockchain technology which maybe a good news to take from this.They have to analyse the possibility of reducing the centralize things if they really want to take those fake products.
