These guys have the hardware and traffic capacity to do this at minimal costs. For the low-ish cost of running high quality scaled-up relays, the tech giants can potentially gather location metadata to match to our public notes across a range of micro applications. I think we will see them leave their walled data harvesting gardens and adapt their current brands to #nostr if only to get more high quality data on us without having to pay their competitors & partners for it.

Beware the high capacity, low latency, free relay operators of tomorrow.
