Apple's not on trial here. They're also on trial for the sorts of things you mentioned, as is FB.
It'll be interesting to see if the courts actually enforce the law, or if these cases get decided on political influence instead. Previous testimony in this case is pretty damning for Google, since it implies their ad business is built on multiple levels of fraud. That ought to be enough to get them to lose the case.
Time will tell. Happily, it's possible for all three of those players to be found guilty. It's not an either/or situation.
