Moving away from a few megacorps would mean consumers have choice in selecting an alternative provider who takes privacy and security more seriously. Today that choice doesn’t exist because Google, Amazon, Facebook, and other big tech companies don’t face competition either due to a traditional monopoly/oligopoly traits, extreme capital advantages, or network effects.
Customers have the choice to not use Amazon today, but how would you give them visibility into who takes privacy and security more seriously? Is Walmart safer? Target? How about my local retailer that only takes orders by phone and types them into a spreadsheet on a poorly protected computer?
