I feel for this. I run a free website, I sell physical books and give away the digital books for free.
The content on the website requires in person data collection, it's very expensive. Yet after a few years the data has changed and could use updating. Sometimes people send rude emails that the data is old. I explain that I can get it updated for $30, and there's a donation button.
I'm personally not interested in updating the data, the prices are similar to before, everything went up in price, the best values are still the best.
Just a reminder that the Physician Cartel in the United States is downright dangerous.
I wonder if a lawyer could do a class action lawsuit against the AMA members. Drug addictions and unaffordable healthcare is some sort of manslaughter.
