If you want to know the real story, you could call and ask someone at Logitech, but the person who was in charge of the Digital Products Group was moved to another area because, as he told me, they were selling so much more conferencing equipment that it really didn't make sense to continue when they needed all of their resources for the products that were selling. Also, the amount of time and personnel needed to support remote control systems is huge, compared to conferencing devices like cameras/mics, keyboards, mice, etc. He wasn't happy about them pulling the plug- he had devoted close to 13 years to bringing Harmony back from the dead and trust me- they were on life support WRT the problems surrounding the H1000 and a few other models. He said it was like losing a child.
COVID is the reason they're selling the conferencing equipment- people couldn't travel to be with friends/family/work, so they telecommute.
I got the call months before they announced it publicly because I was one of the Beta testers for the Elite/Pro/2400 and I raised my concerns about them killing the database and support for it- he assured me that it would be supported for a long time and used their SlingBox as an example- they still support it, even though it was discontinued more than ten years ago and Harmony remotes were far more popular.
