What is something that an industry or many companies do that is counterproductive to their target audience?

For example, hearing aid / hearing loss companies call patients. It’s counterproductive because the patients are the ones who have trouble hearing.

Advertising. I’ll have been thinking about something I want to buy, but then the product or retailer shoves their shit in front of me with advertisements and I’ll give up on it out of principle.

Where are you getting ads? I have it all blocked everywhere.
