Yes, that is what I am saying. Google has set a precedent but not a legal one. So leading back to the question there seems to me to possibly be a case that Apple has a monopoly of sorts and that it is not allowing proper competition because of the power they hold to arbitrarily delete a developer's app without recourse. I don't know if the argument would hold up in court of course and it's certainly not a straightforward argument for reasons you have pointed out, namely people can switch to Android, but I think it should be tried. As for what is wrong with Android - nothing really. I don't use it as I prefer the iDevices so far but if Android does at some point become dominant then what is to say they won't try and close off the market in a similar fashion?
I do now understand what you mean as far as a legal precedent is concerned, but if a ruling were based on the idea that Apple had a monopoly then by definition it wouldn't apply to anyone else.
[edit: removed point about Apple not having a monopoly]
