It will not be enforced by an overworked regularly body, but by customers suing software companies.
No reason for the government to investigate proactively (as long as the government was not affected).
And yes, part of both the GDPR and the CCC proposal is effectively weeding out those whose business model is solely to undercut legitimate competition by putting their customers at risk of losing control of their data or of wasting money on products that are effectively a danger to their data sometimes not even a year after they were bought (looking at you here, cheap-ass Android phones).
I suspect that this is intended to be a single rather than double negative, or did you mean to assert that GDPR was universally recognized as a complete failure at limiting bad behavior?
