I’m not convinced that the solution requires a non-profit, but at least “not-for-profit” & designed to make corporate exit strategies not possible except to avoid bankruptcy. Design solution space includes benefit corp, revenue-backed financing, participative equity & governance.

From my brief analysis of this attack, it is cloud-based services primarily on non-dedicated hardware that may be vulnerable.

Replying to @hrdwrknvrstps
Presumably if you control the dedicated hardware (your own or in the cloud) you are less vulnerable until compromised some other way. However, unless you have a hypervisor that isolates threads, which is not common in cloud, you are vulnerable to other VMs not under your control.
