RPI -- even rpi2 -- is really underpowered for supporting Bitcoin Core-- it's embarrassingly slow compared to other inexpensive ARM systems. Just last week Gavin was arguing for unsupporting all 32-bit systems entirely; though I believe everyone else working on Bitcoin core disagrees, it's not great to be spinning up new systems which are at the very edge of whats supportable. Not all arm cpus are equal, and you can easily have order of magnitude differences in speed with the same nominal MHz.
Many SD cards also have very low performance and write endurance. Esp with the low memory meaning the node cannot cache much, I would expect Bitcoin core will wear out the SD card somewhat quickly unless special optimizations are made to reduce the amount of write activity.
Because of the slowness of it, the vendor here ships with a "trusted" blockchain preloaded, instead of verified from the network. The result isn't easily verifiable, so your trusting that the source (or someone who has compromised their systems) isn't backdooring it in some way-- thats a risk even the developers of Bitcoin Core wouldn't ask you to take with the binaries they put out, Bitcoin core binaries get verified by a public reproducible build process.
It's great for people to run nodes; but you should run nodes in ways that don't introduce more single points of trust in the network; adding more nodes that ultimately depend on trusting one person or another isn't much better than people just using the node that trusted party is running.
