This is extremely unlikely - I wouldn't lose sleep over this. This will only happen when you're doing something controversial/illegal and your registrar is actively trying to legally get rid of you.
But per the subject of the article I think it's worth taking very seriously from multiple angles. Domains are something a lot of people care about for a very long time, their entire lives, or the case of a business its whole existence as an entity. My oldest core domains hit their 25th anniversary this year. A lot can happen over the course of decades, including vast changes in what counts as "controversial/illegal". The winds of politics can and have shifted, repeatedly, a great deal, and technological advance has for better and very much for worse reduced a lot of gray area and informal aspects of law/culture that people depended on (though boosting others).
If one is counting on "audits are very expensive and thus receive significant political push back" it's worth reflecting on whether another 25 years of AI and a host of developments might change that. Could the subject of EU domain ownership at any point become a hot topic? Are there possible financial/social incentives that might push someone to make it a hot topic (absolutely!)? Etc etc, but I think part of the point of the article and certainly something I've come to consider more myself is it's worth taking a longer view more often when considering foundational stuff.
Caused me some grief post-Brexit when my firstname.tld domain happened to be some French islands and AFNIC started indicating they'd enforce it. Fortunately I have the .uk now.
The way this comes about is interesting. First up the EC (the predecessor entity to the EU) is a trade bloc, so it wants to ensure you can move say money and goods around, not much use being a trading bloc if it's there's a lot of taxes and paperwork to move your partly finished Doodads from Germany to France, then when they're finished ship them to Italy for sale. But wait, if we can only move money and goods we create a race to the bottom, the workers would be trapped, so move production to wherever the most desperate workers are and pay them as little as possible. That doesn't sound like we've made anything better. So they say workers can move too, if you want to live somewhere with better pay, or a nicer climate, that's cool. And then the EU's court says well, what exactly is a worker? Is Bob a worker if he just moved to your country hoping to find a job? Does he get to bring his elderly grandmother? She's not going to get a job, how is she a worker? So they decide no, not just workers, all people. All EU people are welcome to move anywhere inside the EU.
this is not true, it is still "freedom of movement (for workers)"
the granny example is explicitly not permitted unless they have sufficient funds to support themselves without the target states' assistance (meaning independently wealthy)
you can be deported otherwise
This is totally wrong.
The granny can get her pension anywhere in the EU, no "independent wealth" required.
There are some restrictions if you have no means to support yourself and require benefits, but the restrictions are definitely not as broad as "granny needs much money on her bank account"
Read: https://commission.europa.eu/strategy-and-policy/policies/ju... and links contained therein
your linked page alludes to this, without details
> In order to stay in another EU country for more than three months, EU citizens have to meet certain conditions depending on their status (for example worker, self-employed, student, etc.) and may be asked to comply with administrative formalities.
if you follow the wizard on your page you get this:
https://europa.eu/youreurope/citizens/residence/residence-ri...
(Just curious; I know this is a tangent!)
Tiny nit (and I only bring it up because it is relevant to me), but you can also own a .eu domain if you are a citizen of the EU (or EEA), wherever you are resident.
This rule may have been brought in as a result of Brexit, as the Europa website says:
> Previously restricted to residents of EU/EEA countries, any EU citizen can now register a .eu domain name wherever they are in the world.

The point still stand, of course. It was (and remains) a headache for a lot of people. I still haven't told my registrar I no longer live in the EU because although I am (as an EU citizen) legally entitled to my .eu domain, I don't trust them to understand that.
