Should be:
>You can run ZFS and Btrfs without using ECC memory, it is definitely possible, but you shouldn't run ANY filesystem without ECC memory.
It cannot be stressed enough. Friends don't let friends run computers without ECC memory.
Almost all homebrew kits ship boards which are non-ECC.
You have to explicitly configure ECC as an option, eg when ordering a NUC.
If you want to make this true, you've got to confront the problem that people go to generic, cheap SBC platforms to run their home NAS, and they are almost never ECC.
My work ZFS is ECC.

Wow. Placing such products in the market without any prominent warnings (or worse, making promises of reliability) should be considered criminal negligence.

I thought it was just a luxury feel good investment, but the longer I run without errors, the more real the problem seems.
The larger the memory capacity, the higher the probability of bit flips, so that likely plays a role.
This post is testing a known bad thing, that comes with warnings, and confirming that yes the well known problems are real. Waste of time.
Ok. So what's the recommended approach? Dump the metadata and start hand culling from there?
If the tool doesn't exist,it just not yet ready.
