I doubt you can force them to provide the service with the original terms, but you might be able to ask for a (partial) refund. If not today, after a week of verbal abuse they will receive for this online.
As I understand it this bypasses a "please do not read" level of protection on cheap microcontrollers, not an actual secure element, so only those secrets are impacted that were not properly protected to begin with.
Firefox on Fedora 43 here, no joy, and indeed, randomly broken on Linux (too).
[edit] Okey, so installing the complete Google Noto Fonts family resolved this issue. But I still don't know if relying on a script with almost no font support is any better than what the OP did.
You could allow to pair the part to some central control unit, when the car is unlocked. I don't speak car or cryptographer so so I have no idea about how to go about it, but this seems like a workable solution.
PostgreSQL logical replication only cares about the data. It doesn't require that you have the same database schema - or even a database - on the receiving end. It doesn't know about stored procedures.
You would typically use it for situations where you don't want to replicate your whole database.
You can subscribe to a narrow/specific set of changes (for example if you only care about inserts to a specific table, no other changes).
It has some significant limitations that means, it can't really be used as "Kafka Streams lite":
You can't have different permissions for different publications. If a subscriber can read one, it can read them all.
There is no separate storage for the publications or the subscribers: if any subscriber is slow/stuck/offline, it will hold back all your WAL for the entire database cluster.

If you want an exact replica of your database, you have to use the "physical replication". This still doesn't specifically care about stored procedures, but it replicates data and schema change exactly.
