This seems like a good thing. As they state, instead of just using OSS they'll contribute back to existing projects and likely release some of their own stuff.

Hopefully they stick to it

At Mercedes-Benz, we are confident enough to know that we have some of the best and most brilliant engineers in the field, and at the same time, we are always curious and keen to learn from everyone out there. So please forgive us if we don’t always get everything right with regard to Open Source from the start. As a company whose core business has not traditionally been software development, we still have a lot to learn, in particular from those of you who have already been walking this path before

This just feels weird for a company to officially state? Maybe im just too use to tech company/startup speak where AGI is literally 2 days away

This is from 2021, why post this now...?

Sounds like hell is freezing over...

But you might have noted that weather patterns are becoming a bit strange recently.
