It is marketing trick to hype people while if any husbands react like this, they are irresponsible husbands.
I don't even need the marketing to get hyped about the new season that's going to start soon. As a Liverpool fan, I'm even more hyped up from all the action from the transfer market already. Even at that, the marketing
did not lie because clubs that end some of their matches with an upset would likely upset husbands (fans) of said club.

Bournemouth is very less likely able to beat Liverpool but an opening match of a new season is always risky for all clubs. Preseason training sessions, friendly matches, new players and possible tactical changes can make their first matches are a little bit uncertain in performances and results.
Agree with you that Bournemouth won't WIN Liverpool. The second game is also as risky as the first. As a matter of fact, it's the first few weeks as all these will have a clean slate and we don't know teams that are in-form yet.
It is likely that some teams with players in their squad haven't found rhythm yet to win games from the get-go.
