Working in ad-tech I know these problems are ubiquitous but apart from trying to patch these issues when we notice them in whatever in significant ways we can what else can you do?
If they’re deducted $0.15 from income, paid to you, on spot each time they query that information, or if it adds 0.015% to probability of their stock crashing in that quarter quantifiably, then I’d expect it’ll be gone forever before any of their C-class stands up for some coffee next time. The reality is roughly reverse of that.
What I am describing is a destructive change to revenue streams for ad companies. That is as nonsense as reversing direction of couple major rivers and I know obvious open question will be how in the world.
