In reply to Siward:
When they announced the TB of free storage I set up my phone so that all photos were backed up onto flickr once I was connected to wifi, so I have lot photos there. I'm sure well over a 1000 too (just checked 5,922!). So I'm now going to have download them all and store them somewhere else I suppose.
I can see their argument that people using the site for storage is different from how it was first set up, but I'm sure they advertised the 1TB thing back in 2013 as "forever, for free" so it's annoying that they are going back on that (I'm sure in the T&Cs it said somewhere that actually forever and free until they change their mind, so I'm not making a legal claim, just a moral one!).
