Promised 'brief weeks' delay resulting in actual months raises questions Netduma needs to address and at least not fool new potential customers, who will buy R1 hoping to get DumaOS on it. Netduma's Project Management team should absolutely have a development schedule for DumaOS for R1 and it's a shame they don't share it with us, their customers.
Is the development of DumaOS completely cancelled for R1? If not, then give us the schedule.
Does partnership with Netgear block the deployment of DumaOS to R1? If so, find a way to evade it - give us an open beta, leak it to github, whatsoever.
Concerned that DumaOS will be pirated and ported to a regular 50US Mikrotik? You should have foreseen this and your customers should not pay your shot.
