Another thought on that point: Why of all things is manufacturer approval so important? We know manufacturers often don't work for - or even work against - the interests of their end users. Manufacturer approval is not an indicator for security - as evidenced by the OP article.

If anything, we need independent third parties that can vet manufacturer and third party software and can attach their own cryptographic signatures as approval.
