Actually this guy is correct: What Ubisoft is doing here isn't false advertising, it's fraud.

False advertising is a very specific thing: You say something that isn't true in an ad or as part of your product's packaging. Like saying your product has a USB C port when in reality it has a Micro USB port and comes with an adapter. Companies that pull stunts like that rarely have legal consequences but technically it is against the law (why there's not usually legal consequences is because most retailers will refund a product within 30 days without any penalty to the consumer).

Ubisoft is giving reviewers a different product than what they're planning on giving to consumers. It's like going to a car dealership, test driving a car, ordering that model, then when it finally arrives it's a completely different car (e.g. smaller engine, different/weaker/flawed parts, etc). Case law is filled to the brim with scams like this. It's one of the oldest and most widely-repeated types of fraud that's ever existed: Bait and switch.
