I wasn't part of that battle. I fall into the camp of believing that clientside logic is often preferable to serverside logic, because users are more able to inspect, modify, and archive locally running code. So not only was I not a part of that battle, I was actively encouraging people to make your life worse.

But I am a part of this battle.

I don't want to start a fight about Javascript; that's a complicated issue. I just want to point out that the "we" you refer to in the privacy battle may be a fair amount larger and more diverse than the "we" was in the Javascript battle.
