A $10 Pi node does more damage to the network than good. It barely gets to download and verify the blocks, let alone share them with other peers. I've tried it, and it's a pain in the arse.. it barely lets you even download and build Core from source. So why run a node you cannot do anything with? Just to add it up to the total of running ones?
It depends what kind of Raspberry Pi device you are using for your bitcoin node, and I know some people who are using Pi4 and run full and pruned nodes without any issue, but important thing is to have enough RAM and solid hard drive.
I don't think you can't expect to run Bitcoin on something like Pi Zero or any other devices with less than 2GB RAM, and I am not sure what kind of Raspberry clones he is talking about.
Some old and forgotten computer could probably do decent job of running a node with enough ram.
