You wouldn't DoS a car

Sometimes whether a thing is an attack or a defense depends entirely on perspective. The motorcyclist could be trying to prevent his motorcycle from getting stolen, but the car owner can't go anywhere now because the motorcycle is anchoring him in place. You could make a lot of arguments about the motorcyclist knowing better, but this site has seen cars chained up as if they were bicycles, so I don't doubt this could have been a sincere attempt to prevent theft (even if it is ridiculous).

As long as ad companies fail to crack down on malvertising, ad blocking remains a necessary security measure. Malware should not be the price of viewing web content.

125 million phones could cover more than a third of the population of the entire United States, and yet I've never even heard of the company Kochava before.

If you've ever seen anything like this then you've encountered geo-blocking, which is one of the few remaining good reasons to use a VPN. Unfortunately there are no VPNs for real life, so this is going to be like a splinter in people's minds.

No clicks for you

Of course heartless corporations are going to double-down on their toxic business practices, but don't listen to their arguments.

This is quite an apt comparison. "Investing" in cryptocurrency is very much a gamble, and there are many ways for you to lose everything. Maybe it would be safer if people treated it like gambling instead of investing, and only put into it as much money as they can afford to lose. Of course there are still people with gambling problems who lose everything that way too, but at least people would have a better idea of what they were getting into and what kinds of risks are involved.
