I take it you have flown both Y and J on Scoot. Definitely LCC, but they are hardly an embarrassment.
My brother, his family, and my mother all have. I don't think they used the word 'embarrassing'. Slow, poor service, definitely NOT business class- what business class gives you only one cup of tea and then makes you buy anything beyond that and doesn't bring you another water when you ask for one. Food wasn't up to standard of Qantas economy.
Economy was what you'd expect in a LCC. Tiny, uncomfortable seats, food about what you expect- cardboard essentially.
So no, not an embarrassment. Just not decent.
