This is the crux of it. Should people expect actual unlimited data? Maybe not, if you’re tech savvy and understand matters on the backend, but also I’m fairly sure there’s a dramatically greater burden on Google for using the word “unlimited”. If they didn’t want to get stuck with paying the tab for the small number of extreme power users who actually use that unlimited data, then they shouldn’t have sold it as such in the first place. Either Google actually clearly discloses the limits of their product (no, not in the impossible to find fine print), or they accept that storing huge bulk data for a few accounts is the price they pay for having to actually deliver the product they advertised.
There are in fact a huge number of reliable counters to drones, including but not limited to anti-aircraft gun systems, anti-aircraft lasers, RF jamming devices (especially effective against cheap/makeshift drones), and several more. Drones are currently an emergent threat without a robust countermeasure scheme, but given their massive role in the Ukraine war that is not going to go unaddressed for long. From a purely mechanical standpoint, small drone munitions are also physically very vulnerable, making them readily destroyed by anti-air autocannon fire or even laser weapons if you assume RF jamming will not solve the problem.
