These companies can work on building and then actually distributing more secure operating systems. This won't fix problems like social engineering, but it will prevent/harden a ton of other attack vectors. Since it allows much more fine grained control over data and resource access than contemporary popular systems, https://en.wikipedia.org/wiki/Capability-based_security https://en.wikipedia.org/wiki/Capability-based_security and the concept of "hollowing out the attack surface with the https://en.wikipedia.org/wiki/Principle_of_least_privilege https://en.wikipedia.org/wiki/Principle_of_least_privilege" can't be mentioned often enough. Some specific projects to mention are https://en.wikipedia.org/wiki/Fuchsia_(operating_system) https://en.wikipedia.org/wiki/Fuchsia_(operating_system) ,https://en.wikipedia.org/wiki/Genode https://en.wikipedia.org/wiki/Genode and https://en.wikipedia.org/wiki/Qubes_OS https://en.wikipedia.org/wiki/Qubes_OS If these don't make it to the mainstream, it is the responsibility of FAANG companies that at least the concepts/mechanisms contained in them do, in other systems. To provide the world with a secure computing substrate.
