If data on S3 is crucial for business to be alive? Of course! I would even think about writing data to 2 separate storages in real time to be able to switch easily. 3-2-1 backup is a no joke, especially when it's your business, not a hobby project. Having DR too. And it's not a legacy, 20 years old system, so it's much easier to do such plans and test them.

Do you run a multicloud system too? In case the AWS account gets shut down by billing issues?

You don't have to run it a entire duplicate of your current infrastructure, just plan for it to happen (depending on impact to your business). Then it means you can think about doing it after a few days of downtime, maybe earlier depending on difficulty/impact.

But, yes, you do have to plan to run it elsewhere and consider wether various features may make it harder for you to move on. vendor lock-in is a known business risk

Running multicloud (at the same time) is for availability not disaster recovery. Just having another copy of the data outside is good for DR, even if you have to redeploy everything manually in a hurry.
