You are free to sue Meta. If you can demonstrate harm, you will win. They may pay you off handsomely to avoid seeing the case go to trial. It's because we are free that the option exists. Is that not better than letting government decide which companies you can and cannot sue?
This assumes a perfect justice system, and that’s not the case.
Regardless, the judicial branch is a perfect example of the limits of freedom in practice, and the legislative does, in fact, decide who one can and cannot sue.
You'd have to have a real lock on it to get anybody but a shady lawyer to take it on. It's very unlikely that you'd be able to do that under almost any circumstance. Yes, the potential payout would be large, but the expenses the law firm would have to pay in the meantime, and carry for the many years it would take for the lawsuit to come to a conclusion, would also be very large.
It would be a huge gamble and reputable law firms would have to feel extremely confident that they wouldn't end up on the losing side. That's a big ask regardless of how good you case is. These tech companies have enormous warchests, can drag these things out essentially forever, and the odds they'll find a technicality that would blunt the lawsuit are very high.
