You're right, there's risk in any action. The solution is to accept the risk, not to harm others while trying to protect yourself.

By blocking adverts, you're harming the people who make the things you like, in direct proportion to how much you like their content. The more you visit their site, the more load you make them pay for without giving anything in return.

If you're okay with harming others to keep yourself safe, and harming your ability to consume additional content from the people you want to consume content from, then fine. Continue to block ads. But know you're part of the problem, and are being selfish.
