Lying about the reason for a go-around in this PPRuNe day and age will bite you in the behind. It’s a big no-no. And honestly, why would you lie about anything?
Well the same airline did lie last year about a delay that they blamed on ATC to try to avoid EU261 payout. They were unfortunate that there happened to be "someone in the know" on board who proved that not to be the case. The ATC union subsequently challenged the airline to rescind the statement but I believe they wouldn't. Not sure how many actually managed a successful EU261 claim
