Forbes forces readers to turn off ad blockers, promptly serves malware

Joel Hruska, writing for ExtremeTech (emphasis added):

For the past few weeks, has been forcing visitors to disable ad blockers if they want to read its content. Visitors to the site with Adblock or uBlock enabled are told they must disable it if they wish to see any Forbes content.

What sets Forbes apart, in this case, is that it didn’t just force visitors to disable ad blocking — it actively served them malware as soon as they did.

At what point does enforcing the use an ad blocker become part of company IT policy to help defend against malware?
