> With a class action you have far more people to fight on your side, making cross X a lot less scary, if it ever gets to the trial stage.
That's not how class action lawsuits work. It's highly unlikely that 'women and LGBT persons of all genders who were abused by shitty bosses at Uber' will be found, by a court, to be a class. The class-action will be dismissed before it even gets to determining wrong-doing.
You can have a class action lawsuit over your employer, say, stealing wages from 10,000 employees.
You cannot have a class action lawsuit if 12 people have been harassed and abused by their managers. (The fact that the practice is widespread will impact judgements, but it does not mean that 12 people form a 'class action'.) [1]
Even more importantly, sexual harassment cases by their nature, require each case to be evaluated on its merits. Just because Claire, Adam, and Barbara have been abused by their bosses, doesn't mean that Donna can piggyback onto the lawsuit, and claim damages, without having her case examined as thoroughly as theirs.

No, it's not - not if you lose. If they win the case, Uber can, and almost certainly will countersue. (For PR reasons, they would prefer to avoid suing you if you just complain on your blog.) The first Google hit for your name will be about how you sued your employer, and lost.
Yes, there is the social benefit of these cases going to trial (Preventing future abuse in other companies), but not everyone wants to be a martyr.
