While I am all for the removal of obscene adverts that are plain rude, if everyone blocks ads, companies will literally just start blocking people who block ads. I hope for one day, or even one week, major websites would do this. It's that or all sites hit the eventual pay-wall. Block ads, got no account? Sorry got no content either.
It's like people think all internet related activity is free, or that the money they give to ISPs somehow makes it to website owners and that entitles them to see everything on the web. Here's a hint: it isn't and it doesn't.
