You bag those big tech companies not being "decentralized" but how is LEO any different?
Khal controls everything and he depends on centralized tech to deliver it all to users.
It's great that he is finally developing his community but it's not at all resilient. It depends on other things to live. Making it also very susceptible to failure since there is so much out of the control of Khal.
If something happened to those backend things or even Khal. No one has the ability to relaunch Leo anywhere else.
It's exclusively Khals operation.
