Imagine I sued you on the basis that the house you are living in is stolen and isn't yours to inhabit. Would it be fair that you can't live there while a lengthy court process figures out the truth?
In special cases, the judge can issue an preliminary injunction where a party is compelled to do something (or not do something) while the court case is ongoing, but the bar for that is pretty high.
If you sued me the case would not last 4.5 years, because a normal person doesn't have the funds to sustain a fight that long. That's the entire point of the gripe - corporations can extend these fights indefinitely and they will because it's profitable for them. That's not a good system for getting companies to act accountable for their choices.
