I have been wondering the same. I feel it is connected in some way. The article mentions CITRIX as a Remote Desktop solution company and that is true. What it does not mention is their enormous presence in network ADC (Application delivery controller) access gateways, multi-factor Authenticator access control. All major cloud providers and most large websites and companies use these network devices.

Citrix ADC is an application delivery controller that performs application-specific traffic analysis to intelligently distribute, optimize, and secure Layer 4-Layer 7 (L4–L7) network traffic for web applications. For example, a Citrix ADC bases load balancing decisions on individual HTTP requests instead of on long-lived TCP connections, so that the failure or slowdown of a server is managed much more quickly and with less disruption to clients. Its feature set can be broadly consisting of switching features, security and protection features, and server-farm optimization features”
