I expect that the issue is more likely that 99.999% of people are using the service are doing so "normally", but the 0.001% who are not are using disproportionally large amounts of data/abusing the service at the detriment of others etc. I have no doubt that there are people out there doing shady/dodgy things to abuse the free "unlimited" storage and pumping in huge huge huge amounts of data or have hacked up some crazy system to use it as some sort of hacked-up rsync, using it for bulk image classification instead of spin up their own service etc etc etc Charging a relatively small fee to high users while leaving it free for the vast majority seems like a fair way of trying to slow down abuse to me - I think they did the same thing with the Google Maps APIs a year or two ago (i.e. turn down the free tier significantly and make it cost a small-but-not-zero amount to stop people abusing it) I currently pay £1.33 a month for more storage - so like half a starbucks coffee. Seems fair to me considering how many years of photos I have in there.
