I know one example of advertising that I liked: the creators of Penny Arcade had only advertisements for computer games that they liked. And they made those ads in the same art style as their own comic.
Advertisements are good when they’re an honest endorsement. Any others are inherently deceptive and often invasive.
Russia will continue fighting as long as they can and Putin is in charge. The only two ways to end the war are to break the Russian ability to attack, or to get rid of Putin. The former is significantly easier than the latter (though it might lead to the latter).
So the EU kicking all Russians out of Ukraine would de-escalate and end the war. Not doing anything means Russia will continue its attacks and find new ways to do even more damage.
