Yes, they do read the forums. you may remember a few months ago we had people from the Windows 10 group actively taking part in the forums here, collecting bugs and supporting the early builds.
However, they have tight restrictions on what they can say where. And they certainly won't comment on leaks and rumours.
Your remark about Microsoft's love for Apple/Android and sidelining WP is pretty baseless (although you probably got this impression from what you read). Microsoft supports its customers, regardless of the platform they use (something that Apple and Google doesn't do - they'd rather only suit themselves). There's no sidelining of Windows 10 mobile - maybe you've forgotten how many updates for key apps we've had.
The key issue is threads like this that are simply spreading misinformation (or FUD, if you like). Sometimes people need to take a step back from the negative hype and think for themselves.
