It is owned by Xavier Niel, so yes, they are.

Personally, I've not used OVH, so I cannot judge. But here is how I would rate Scaleway.

Pros:

- They are really really cheap! This is not just for the VMs themselves, but their VMs come with NVMe disks and comes with uncapped networking

- Their customer support has been phenomenonal, and this was when I was on their free tier support

Cons:

- They are only limited to 2 regions, Paris and Netherlands

- I've seen their VMs become out of stock quite often

Personally though, their pros far outweigh their cons, so I would very much love to see them expand their service.
