Mint.com removes users ability to delete accounts

They moved it from inside their app to inside the intuit website and ask that you wait 45 days to view any data they might be deleting, and then actually deleting the account takes another 45 days. In other words to preview your data and then delete it takes 90 days.

All of their help articles still reference the now removed method of account deletion. How is it legal for companies storing massive amounts of personal information to not have a reasonably working account deletion mechanism? and out of date help articles to boot.

Is this a common practice these days?
