If there's a mode where it can render all non-ad text without even downloading anything else into a users machine, it'll be a slam-dunk.

With optional further granularity to include images, then audio, then video.

User-selectable filtration would be nice but if it was done right the defaults could be a moving target based on collective data and it would be continuously adapting to the ad onslaught as it evolves in real time. To users' advantage even as the unfiltered ad landscape evolves toward worse user disadvantage.

Default built-in prompt "remove the crap", you'll know how successful it is by how much users rejoice.

Ideally would be very sparse on any data uploaded from users machines, so that it was always measurably insignificant when it comes to privacy intrusion compared to things like Chrome. Overwhelming advantages in bandwidth usage and memory consumption are on the table just for the taking.

It would have to stay ahead one step more intelligently than an ad-based company, and it could actually make the world a better place in its own way more than people might have expected.

Ideally OpenAI should be able to afford it, and it could fly off the shelf with no need for OpenAI to become an ad company itself. That's a strategy which Google might not be able to retaliate against without curtailing massive amounts of its own ads. Which would be fine, Google should be involved in making things better for the user too. Maybe all they've been needing lately is a little serious encouragement.

I did kinda think OpenAI had gotten together with Microsoft to make things like this happen a while ago, but I guess people can't always get along, much less come to agreement on what makes the world a better place :\
