The goal was to attract Twitter refugees. No ads helps sell the "greener pastures" the users were looking for.
Once those users are comfortable, Threads can do whatever it wants. They know how much it took to get Twitter users to leave Twitter.
People acting like Meta launched Threads out of the kindness of Zuck's heart are dumb as fuck. Threads has the same goal as Facebook: to make money selling your eyeballs to advertisers and your metadata to data brokers.
I have a 60TB media collection, so this would end up costing $600/month.
Instead, I back all my media up to LTO-6 tapes, and store them at a storage unit.
LTO-6 drive: $400 10x LTO-6 tapes (62.5TB): $200 Small off-site storage unit: $30/month
