Everyone is of course completely free to make their own decision about whether the game is for them or not.
Some people love the companions, some people hate them, the majority seem to be somewhere in the middle - including me, though I'm sure I'm much further towards the positive than many. And there's always the option of the custom party workaround or hirelings if companions are the only thing bothering someone about the game (which the poster you quote doesn't seem to be aware of). Personally, given they were never going to please everyone, and chances are that pleasing the folk who aren't currently happy would mean that many people currently happy with the companions would become unhappy, I don't think Larian have done a bad job at all.
But if you've decided that what you've heard about companions from reading other people's views is a dealbreaker, and the rest of what you heard about the game wasn't appealing enough to counterbalance it, chances are you've made the right call for you.
