It is marketing tool that is creating interest. People, with the ability to influence buying decisions, reads the download page hopefully fairly often.My grip about this is Mikrotik's product management. Who updates a download page before make some announcement, someplace. Why make customers read the tea leaves?
Totally makes sense they'd port RouterOS to Ampere, since it does seem to be trending. But still be same RouterOS. So all it changes is price/performance calculation when picking gear – which are already pretty good with Mikrotik. Now easy to imagine ampere might have a lot benefits over x86 at the high end.
