"The intercept reads:
"A bird is flying towards you"
"A bird is flying to us?"
"Yes. One so far"
"A scout [recon plane] or a big one?"
"Can't see because of the clouds - too high"
"Roger"
This sounds much more like a spotter reporting a visual observation of an incoming plane (assumed to be either a recon plane or a militar transport), than an order to be ready to shoot down an incoming civilian plane."
yupp, they didn't have auxiliary radar vehicle so had to rely on spotters, it's quite clear they didn't have any intention and it's quite clear it wasn't any conspiracy being it from russian or ukrainian side
