Question

Why do “hard” bristle toothbrushes exist when every dentist seems to recommend “soft”?

Answer 1

Because some people buy them, and stores make profit from them.

If dentists convince enough population to stop using hard brushes, then stores will stop selling them due to lack of demand. Or if they convince the government to ban them.

Or if there if a lifetime user of a hard brush manages to successfully sue bursh-makers over damage to his gums. He would need to prove that damage was caused by brushes, and not food or lack of nutrients, so it would be an uphill battle.
