It is bad, but today's no-stick coatings and ceramic pans are bad in their own way. Most people don't know the newest coatings release particles and chemicals into their food. Beware of Chinese-made non-stick ceramics and coatings.

The non-stick may be convenient but it is setting us up for later problems. Metal pans may be more work but are healthier. However copper does release heavy metal into food too.
