That's bizarre. If anything, Amazon ebooks are worse than anything you can download, as Amazon retains some ability to remotely erase or alter them if your device remains connected to the internet, which pirated books never will.

That is not a problem with the ebooks it is a problem with using a Kindle.

If you download your book from Amazon to your disk e.g. in Calibre Amazon can't touch it.

I have many amazon books and I read then in pub based readers on my iPhone.

Even on the Kindle I think I am safe as I tend not to use the Amazon link but upload via Calibre so what is on the Kindle does not match what Amazon thinks I have on the Kindle.

Correct. I do not open amazon e-books in the Kindle app. I jailbroke my kindle to allow for OPDS connection to my calibre server, and put it in airplane mode when not copying books from the server.
