My intuition is that it will not change. I feel like there are two classes of people who use Brave:

1. Hype driven people who crypto ads work well on.

2. Privacy driven tech people who are pretty much non-monetizable.

Self-service ads are useful for small to medium-sized advertisers who want to target specific niches with pinpoint accuracy. If Brave's whole thing is that they protect your privacy from targeted ads, and also they lack the scale to be useful for non-generic ads, then I'm not sure any of this makes sense.
