Its possible that it happens, but from my admittedly limited anecdotal experience from seeing a half dozen or so people claim that they were banned for no reason and then taking a look at their comment history, they were absolutely banned for a reason.
Do you have an example of someone being banned simply because they shared an unpopular opinion?
Also "not true in general" implies that you seem to think that its a widespread problem and banning people simply for having an alternative opinion is one of the more common reasons people are banned. On HN that is something I find hard to believe.
