"Everything they can" isn't the same as "everything." "Everything they can" means "everything they can get away with as a long-term-viable business strategy." For an airline, safety is not one of those things. For OVH, though, the "safety" of their servers (i.e. availability/durability) is one of those things they can skimp on — because unlike for people, for servers, "safety" is just another fungible thing to optimize as part of OpEx. One of the fundamental tenets of IT operations is that hardware can just fail, datacenters can just catch fire(!), backhoes can just cut cables, etc. — and so businesses that care, architect their stacks to be resilient to these failure modes, using multi-AZ replication and so forth. And if everybody who actually cares is already doing that... then it really doesn't matter if your DC goes up in smoke. (And also, to these same companies, low cost can have a "safety" all its own. Rather than lowering OpEx, you can instead see the calculus as: for the price of one vertically-scaled AWS instance, you can get four equivalent OVH boxes in different regions, and replicate between them. Which one of those options is "safer"?) Mind you, if anything got burnt up that had real SLAs on it — for example, if they were offering an DBaaS service out of that datacenter — they'd be in trouble. But some leased bare-metal boxes? Nah.
