I didn’t imagine that I would stir up quite so much interest when I decided to ban query strings!
When I said, “if it isn’t there, it’s probably for a good reason”, I was fully aware of native apps, and decided to gloss over them, because I doubt (on no evidence) they’re so significant for me, and things like email and feed readers may well be web apps anyway. And because I’ve tended to fine nuance in the past, and am trying being concise instead.
While thinking about it—is it possible for a browser to know which app sent it the link, e.g. androidapp://com.example.app? Because that’d probably be a perfectly reasonable referrer, if a browser wanted to send it.

Opinionated: I dont get the issue about people (incl. bots) visiting your website, regardless of where they originate from and what url they use.
Publishing something online means I want it to be seen.
Relying or enforcing Referer or query string basically contradicts the intent. Wanting to know where your users come from could be legit but then you basically distort the "public web" aspect to a "public trap" where you try to sneak on visitors.

I don't think the statement is factually backed up. At least I hate native apps.

Anonymity considered harmful these days?

It's not legitimate unless it's signed (and if anybody gives a shit to verify it).

This is a good habit IMHO.
Anyway, I'm thankful to the original post because it was a good reminder to re-review my browser settings.
Honestly I don't understand why the EU focused on the stupid cookie law instead of referers which are clearly privacy-violating.
If you use Firefox I recommend you make sure `network.http.referer.XOriginPolicy` set to 1.
I also dont get why adding 'utm_source=Robin_Sloan_sent_me' somehow gels with his calculation it is 'an expression of digital etiquette: rather than dump a load of anonymous traffic on your doorstep, I reveal who’s linking'.
Theres no actual link to the referring website just some bunch of characters which look like someones name and some of which are in the actual referring URL.
And yeah I'm also thankful also to see that firefox setting.

Neither the ePrivacy directive (commonly called the "cookie law") nor the later GDPR focus on cookies. They are "technology neutral", applying to e.g. URL parameters and HTTP headers too, but just widely misunderstood and badly enforced.

I highly doubt this is true, unless your definition of "app" includes "web browser".
i'm confused, why would you go out of your way to add this tracking info to external links voluntarily? it doesn't benefit you, it just helps other websites segment their traffic?
When other website owners realize how much traffic you send them that is good for you. Maybe they want to sponsor that newsletter if it’s driving a lot of business.
I get adding query strings on links to your own domain, but from the original post, it sounds like the author was seeing third parties add query strings to links to their domain and I don't see what the point in doing that is, unless the entity adding those quey parameters is able to somehow intercept them between the browser and the website (which is possible if they control the browser or a cdn).
If there's a query parameter that you have a legitimate use for, like `q` for searching, obviously you should configure your web server to let it through.
Even in that case, you might want to block unexpected values as early as possible in your stack. For example, if you have a legitimate use for a certain set of `utm_source` values, but someone sends you bobby tables, you probably shouldn't log it blindly.
Ditto for the Referer header -- there's a lot of spam, and some of those strings might even be dangerous. You can't trust any of them anymore.

I want to learn more about this.

Not my vibe
I strongly disagree with a lot of claims here.
