'Running a business' is not carte blanche to do whatever you like to get money, and it does not silence valid criticism. Businesses still exist in society and have to act accordingly. A primary mechanism that society has to enforce rules is criticism and shame.
A business is not entitled to make people look at their ads. If they offer something in a publicly accessible place and they get ad eyeballs, good for them. If they don't, sucks for them. If they don't like it there are plenty of other markets they can do business in.
If they want to charge users with ad-blockers under the Computer Fraud and Abuse Act for unauthorized access for viewing non-protected pages then they should do that. Otherwise, you are wrong.
