There is an obvious creeping issue regarding the privatisation of public space, which is the interesting part here and what we should be pushing back against.

I'm less bothered about using wifi MACs to measure traffic, so long as no data is retained – it can provide useful insight into the number of visitors. Randomisation is obviously in modern devices, but I'd be concerned that older devices won't have the data regarding them deleted.
