RIP Perhaps he missed this memo and sees this as a total competition, which is how I think most users are doing (as you say). Maybe you can be frank with him by sending a PM about this? And point to this one message where you say so in public?
I don't know what can be accomplished by that PM. PianoClack is and always be on a collision course with the digital subforum of PW. Maybe they will coexist, maybe one disappears… No need to apologise over creating a new forum, like Frank (or any one else) does not need to apologise if they still prefer to post there and not here…
