Morals are not defined by respecting the wishes of other people either. You’re right to pivot to common expectations, that’s closer, but when you examine the actual expectations of both the public and the advertisers, you find that it roundly undermines your choice of framing here.
Restaurants are a false analogy. There is an explicit agreement known in advance by both parties, a legal contract with a restaurant when you order, and leaving without paying is a crime. There is no such expectation with ads.
This is cringey and goofy. It’s not a moral issue, you’re really stretching. Even if it was a moral issue, the global known public expectation of ads is that they’re sometimes tolerated and on the whole not preferred. You’re choosing to prioritize the viewpoint of advertisers over respecting the wishes of the public, while if you look at it from the public’s perspective, ads have never been the “moral” choice.
Your argument, of course, is also wearing blinders to the many ways that ads can be actually immoral, for example as a soft bait-and-switch, by offering one thing to entice while delivering something else with an agenda, and the ways ads are often directly immoral by using misleading or untrue information, selling goods and services that are overall harmful to the public, from excessive sugar to payday loans to expensive pharmaceuticals to politics.
