Advertising is a form of hostile content. Advertisers mean us harm. They might have some tenuous moral right to try to expose me to their manipulation, but I am not obliged to co-operate and my moral right to protect myself is much stronger. This is implicit in every form of advertising. You are not doing anything immoral by buying a magazine and then not reading any of the ads it contains.
Arguments against ad blockers require that there are not alternate ways of exploiting content production, or any reasons to produce content other than financial gain.
