I’m saying the very idea that you need to ever even think about this as a defense against the enemy is the hobby. There’s only a battle to be fought here if you want there to be, and most people don’t want that. The impact on their lives is not actually tangible. Ad tech doesn’t really hurt anyone. No one likes it, and at best, it feels a little gross, but feeling vaguely icky is not the kind of tangible impact that reliably drives people to action. What happens to you when Facebook or Google bundle you into anonymized groups of eyeballs and promise advertisers that they’ll show you ads relevant to the profile they’ve built of you? Nothing really. If you think about the way they built that profile by tracking your every move online, then yes, it feels creepy, but that’s it.

But that’s not the kind of privacy we’re talking about. Privacy discussions are largely about ad tech and tracking. The post here isn’t calling people idiots because he thinks Threads is more likely to leak your credit card numbers and nudes. He’s calling people idiots for not caring about tracking the way he does. And the reality is that there’s no real reason why they should care. The argument boils down to just, “c’mon, don’t you think it’s creepy?”. And if I say, “not really”, we’re kind of at an impasse. There’s just no obvious pragmatic harm you can point to to reason them over to your side. You may as well being trying to convince them to enjoy pineapple on pizza. If they don’t already, the game’s pretty much over.

I’d also say that those health issues are much more practically impactful than Instagram showing you ads for luggage when you’ve bought a plane ticket.

Caring about ad tech is a hobby. It’s as good a hobby as any other, but that’s what it is.

A native app offers the most control. Ad blockers are harder to obtain and use.
