I agree Walsh's comment was rubbish, but in his defence and for what it is worth he isn't talking about Froome's reasoning behind his attack. He mentions the reasoning in his second tweet. There are two separate factors here, the way Froome rode away and the reason he rode away. Don't mix them together.
I dont think Miburo mixed the 2. I think you may have mixed them up instead (no worries it is a bit confusing).
The phrase "reason why froome rode away" can be a bit ambiguous in this case. It could refer to Froomes motivation for attacking in the first place, or it can refer to the reason why he was able to ride away. These themselves are 2 different things.
You seem to think Miburo is talking about Froome's motivation for attacking, but he isn't. Miburo instead was talking about why Froome was able to ride away. The reason Mbiuro offers is that everyone else was surprised by Froomes attack and therefore didn't react.
And that is very much linked with Miburo's criticism of Walsh. That Walsh is wrong to read so much into Froome's attack. - He was wrong to read so much into Froomes attack, says Miburo, because Froome's attack is easily explained away by the lack of reaction from everyone else.
Not that it really matters, but i had a few free minutes
