I have done both, I've been loving Zaps and cheering them on while also fighting for privacy at the same time.
I can both love a feature and want to see it built with privacy and self-sovereignty in mind from day one.
The longer we wait to think deeply about how we do this in a privacy-preserving way, the less people will do so and the less likely that it is done in a privacy-preserving way at all. We *have* to build from the ground up with privacy in mind.
