Yes, there is. If you had a group of 100 people and asked what google.com should look like and showed them how Chrome renders the page and your 80x24 modification does that all 100 would say that yours is not expected. You are still too hung up on these technical details of how things are implemented than how the average person thinks of these things.
There is not, and has never been, a social contract that says I have to look at the ads served with any website. If you think there is, then I'm sorry, but you're sorely mistaken.
Similarly, there is no social contract that says I have to watch commercials while I'm watching TV (not that I've watched linear TV in over a decade, but...). I can mute it, change the channel, go to the bathroom, whatever. If you think there is, then I'm not sure what to tell you; your opinions on this are so outside the mainstream that we're not going to see eye-to-eye on this.
We were talking about societal expectations.
>I can mute it, change the channel, go to the bathroom, whatever.
You are free to do the same for websites. You can click the x button on the ad, mute the video ad, or change to a different website.
And those that disagreed would still think it in their heads.
People like free stuff.
