Is this an ad?
Possibly but also plausible is that its a deep joke that everyone is in on.
When googling the company, the marketing slogan that comes up is "Linde is Everywhere" but that works on so many levels. They sell air, air is everywhere. Therefore Linde is everywhere.
They are a company that sells air: that stuff that people breathe. Forget this AI nonsense. Jensen has to constantly pull something out of rear to keep food on the table. These guys sell air. What a business. :)
I don't think Linde™ needs an add, everyone knows Linde™ is the most reliable partner in producing and storing gases in all available purity classes.
(joke off, it's probably not an add, but they were excited to share the reason you see Linde on all sorts of gas tanks all over the place. It's actually quite common and if you see it once you see it everywhere. )
