Often times the backup provider is the hosting provider, whom you have to trust. (This extends all the way from big clouds like AWS and GCE to small providers like Linode and DO). Having an external backup can be unreasonably expensive due to ridiculous egress costs.
If your business can't afford external backups then you don't have a viable business in the first place. And of course egress costs have to be considered when choosing a hosting provider.
This becomes very difficult as your data grows. If you live in AWS world, imagine periodic snapshotting from EBS, S3, RDS(and other data stores), EFS etc. For most people a different DC of the same cloud provider should be enough. If you have to put this into a different cloud provider it is a big cost drain and difficult to manage let alone if you want to have your own physical backups.
AWS has tools around this (lifecycle manager) that you can easily leverage for simple site backups. Or you can roll your own, honestly it is not that hard to take rolling snapshots.
Obviously hosting providers do not make it easy to extract your data because that's their vendor lock.
Also, always make sure you're testing your backups by restoring to a non-production space, and ensuring that customer services are still available.
Gandi has never explicitly said they never had their own backups, just that they don't offer backups as a service. It's entirely possible that they did have backups, but couldn't recover/restore them.
You really shouldn't trust anyone hosting your data. Always have backups!

You can still back up to the same providers' different data center. Two data centers failing simultaneously is very unlikely.

"...marginally more than rolling your own or another cloud provider."
And to "trust marginally more" simply means:
