>why is it still needed?

It's not needed. There are already alternatives that could take its place. Some of them are able to actually show you what data leaked instead of leaving you blind of what was actually included in the breach.

Is there ANY business motivation for any corporation to open such information up sooner than later?

there will be more data breaches.

Google and Apple are throttling hotfix updates (for app developers) as tons of code pushes to their infra (by vibe coders) is straining their system.

The are fixing this by throttling updates to minimum 3 days review period.

so good luck fixing the vulnerability or data leaks in your apps.
