MAN forecast for the 8th (yesterday) was a 10 knot gust straight down the runway.
Pretty sure LGW was forecast to be something like 210 degrees 29G42 wasn’t it??? That’s almost all crosswind component.
Therefore 2 wind shear go-arounds with the option of a diversion to a less windy ‘into-wind’ runway doesn’t sound all that stupid. Don’t know many skippers who’d act any differently. If the alternate was just as bad, then fair enough make a judgement call - but it clearly wasn’t the case!
