And probably you as a customer are a main target of such video, but the fire was such a high-profile case (I think) that this should be more understandable for general audience.

edit: not sure why I got downvoted (and I don't really care that much), I just think that communication from CEO of big company after such event should be clear for everyone, not only for those directly affected.

But ... the video isn't for a general audience. He doesn't have any reason to apologize to a general audience. His customers are the only people that matter in this situation and this video is for them.

Honestly, nobody lost their lives, the impact is pretty much limited to OVH (who need to find a new building), their customers (who need to find new servers and restore backups), and the city of strasbourg (who run the emergency services and presumably will have some involvement in the cleanup). While we're all interested in a "Oh, are we prepared if that happened to our provider?" sense, I don't see why OVH is obliged to provide communications to us, rather than to their customers.

I would expect the communication to be directly targeted to customers not the general public.
