Blockchain is in the open so you don't have to trust one organization. Multiple organizations watch each other. And one organization might quit anytime.

You're right that many blockchain projects are based on one organization, let's say that Porsche project, and they could use a distributed database instead.

"All activities are documented in the blockchain, making deletions transparent." Sure, but Porsche is the only provider of data (writes) and can change the rules. I don't see how others are writing in the same blockchain.
