Usually they make money with extended certificates where they not only offer a certificate for example.com but also certify that it belongs to Example Ltd.

Those extended certificates used to show the company name next to address bars, but I don't think browsers do that anymore.

Both Italy and Austria are EU member states , fall under the GDPR AND NIS2 and while both government(even under the FPÖ) have their downsides neither has legislation that is even remotely close to what the US even have today (and had for decades) and unlike the US both countries still have a very well working judical system and the ECJ.

So. Yes. While not perfect, their situation is massively better than a US non for profit. Total different league. Not even in the same ballpark.

The thing is, the US is already fascist. Austria (current day) would be an improvement.

Also, you know the downfall of Autistici/Inventati - No - check my post history. One of the events that happened is that US owned PIR removed one of the domain names since they own .org. One less US entity, one less point of failure.

I thought zerossl used let's encrypt behind the scenes (for their free certs at least).

Edit: they don't mention that on their website, perhaps they don't.
