Ledger is indeed an issue.

However Peter does ONLY promote storing your bitcoin on it, which would be unaffected by its latest gaff (maybe not so much the others though). He likely has a contractual obligation to keep promoting them on his show though.

Other than BlockFi though I don't think his track record is that bad, plus he now has Swan sponsoring his show.

We all make mistakes and Peter does learn from his mistakes so he's got that integrity going for him.
