Traffic isn't actually that expensive outside of big clouds. No idea where pico is hosted, but Hetzner gives you "unlimited" 1Gps connections with a dedicated server, or a 10G uplink charged at $1.20/TB (plus a fixed monthly fee for the uplink itself).
I have good reasons to believe this is hosted on Oracle's free tier. Apart from the fact that pinging pico.sh points to an Oracle IP, the 10TB limit is consistent with Oracle Free Tier's limit.
