Daily fine will only work if it’s increasing. I’d start him at a million euro per day and double it every 7 days (it would take just over 2 months to reach 1B/day)

It’s always effort vs risk.

Since it’s a do once and forget kind of thing I’d rate effort rather low.

As for risk in the worst case scenario a single service being compromised means all of them are with the attacker getting access to everything those services can access, including all the credentials. Will you make an effort to be on top of all the updates for all services?

As far as I’m concerned: At home all containers for each service get a separate user. At work every container does.

I tried to make Jitsi happen, but given that majority of out customers and vendors have google workspace there is little incentive to not use meet.

Depends on what part of the company you are dealing with - in engineering we’re usually a bit annoyed when anything other gets used simply because meeting software clients for Linux are either shitty or nonexistent.

For general public interactions: Find a place that prints business cards and order some with something along the lines of “I stop being able to speak when overstimulated. Please give me some time. Sorry for the inconvenience.” printed on them. Being able to pull one from a pocket instead of struggling to explain while unable to speak should make it less stressful.
