How is this a bad thing for them? Now they don't have to pay for clicks from people who aren't interested in their services. People who want to hire a lawyer will still click.

The idea for all this content marketing spam is that writing those articles (eg. "how can I dispute a speeding ticket?") is cheaper than buying ads for "speeding ticket lawyers" or whatever. If people don't click on those articles, the whole strategy falls apart.

It might work out for some of them, but they lost the chance to make any sort of pitch to those people.
