Search engine bit is confusing...

Here is how I parse it:

In the past:
When users click on ads in Google search results, Firefox gets some of the money via the well-known scheme, and Google keeps the rest.
No ads are blocked.
No ad-related money goes to or through Mint.

In the future:
Mint have new deals with search providers so that when Mint users click on ads in search results, Mint gets some of the money.
Providers who don't have such a deal with Mint will be removed from the search provider menu in the web browser.
Ads from providers who don't have such a deal with Mint might be blocked.

Have I got that right?

If so, it does seem a bit odd.
