When I tried out Binance it was confusing as hell. Ofc I went there first, but it was too many options, confusing interface as soon as you switch out the newbie mode. Tried to go to support (they had 24/7), was met with a chatbot. Couldn't trigger a real agent. Never came back.
Welcome to crypto, where you have to teach yourself new things, especially exchanging aspect. I think you were a little impatient or uninterested in learning how these exchanges work. Even me, I was once a noob and exchange interfaces were so confusing but today I see no problem after several trades.
Also checked out the link you said, the poster themself withdrew their argument because of these comments:

They have valid points actually.

Valid or not, you need to weigh and see which side has more points. As far as I can see, the negative outweighs the positive. If all exchanges behaved like HitBTC. The count of their scam accusations here would even be higher than HitBTC which is not as popular as coinbase, Binance, Kucoin today.
I am surprised you even opposed the flag. Wow.
