“… Prior to me moving it to its intended position out of the line of sight of other residents, someone took a photo of it & complained to the building committee…”
Sounds like you could easily ignore this and if the committee pursues the matter you could innocently say that the complainant’s photo was from before you had moved it to its final position out of sight and that you had assumed that moving it had addressed the matter.
If it can still be seen, then argue that it is a very normal and reasonable thing for people to have on balconies (just like drying washing 😉 ) and they should stop being so precious.
As I write this, I can see my vegepod out my window. It is sitting on a low retaining wall and, strictly speaking, overlapping my courtyard boundary making a minor incursion onto common property but nobody has ever complained about it.
