Hmm, I'm not sure what you mean by "our platform", but if I post a youtube video, it gets popular, but I get ashamed of it and decide to delete it again, the video will have spread far and wide to other video sites again.

Some for public web pages and the internet archive, for stackoverflow answers/wikipedia entries and SEO rats, and so on.

How is "your platform" going to help me delete my embarrassing drunk student video from the internet's video sites?

The only way "your platform" can do this, is by actively working to block public access to that video in the first place. Then you can have fun (or not) deleting those 20-100Gb datasets. My point is that that means accepting that you're posting stuff to a walled garden.

It sounds like his platform is perhaps a private enterprise platform? In other words, it doesn't sound like Facebook or Youtube where information can easily spread, which is probably a prerequisite for having control over your data.

The company I work for deals with background checks and screening information on behalf of our clients' clients. I could definitely see us safely removing all of that personal information from our system and not being able to recover it. But at the same time, we're a much much much smaller organization compared to Facebook.
