I agree this is a novel interpretation. Could you elaborate on what the computation performed involves ?
I'm of the understanding that you send me ciphertext, I transform it with some operations you define, and I send back ciphertext-v2.
I can discern how this could exfiltrate data safely. They send in a bunch of zeros and I fill in a one for each minute I used this lightbulb, by dynamically creating the FHE circuit to reflect the data saved.
It's not clear to me how this could change my lightbulb. By 'change' I mean 'affect the behavior' or update the firmware or something. I say this with the expectation that the blobs I received and produced are ciphertext on my side, without keys to decrypt it (unlike, say, dvd drm).
