People throw pies at politicians faces as a protest and they're often arrested afterwards for assault, but it doesn't mean they can't do it.
Can you murder someone? Even if you are physically capable of pulling a trigger, I think you know damn well that’s not what anyone means.
Sit-ins are an old protest tactic. They were used during the civil rights movement, in private property. They were used during labour protest, in private property. They have repeatedly been successful at achieving the protestors ends. They have repeatedly, in hindsight, been viewed in a favorable light and broadly seen as permissible. They were frequently, at the time, viewed as illegitimate and impermissible. Of course, there were other sit-ins which failed and were very much unpopular and were unjustified.
We should all be glad that the view of "she should have just founded her own capitalist, nonwhites-only bus company" did not prevail.
(Google's anti-Gazan defense-dealing is the bus company, in this example)
You’ll find a copy of her arrest warrant here: https://www.nytimes.com/2018/06/26/us/rosa-parks-montgomery-...
“It took the police a couple of tries to settle on legal language describing her alleged offense.”

You say that as if we don't all already know that the actual offense was upsetting the order of the apartheid. What took a bunch of racists a couple of tries to eventually settle upon is irrelevant. Similarly, the police in this case may take a couple of tries to eventually settle upon legal language, but we nonetheless all know that the actual offense was upsetting the order of the apartheid. Just like Rosa Parks.
Besides, Ms. Parks herself was impacted by the unjust laws that required her to sit at the back of the bus. It’s unclear how Google’s activities directly and substantially impacted the lives of the protestors here.
To address your edit:
Rosa Parks was protesting the treatment African Americans were receiving, these workers were protesting the treatment Gazans are receiving.
In those cases, it is better to violate the law than to preserve apartheid.
Just like Rosa Parks.
