The sensible answer to this issue is tax reform, to make sure the real world use of tax laws matches more closely to the intended consequences of the tax laws.
However, in the meantime, we can still send a clear message that the behaviour being engaged in is not desired. If words alone will not build enough momentum for change, then people could resort to civil disobedience. For example, Google is dependent on its advertising business, it would be trivial to "legally" damage this (for example, running bots that clicked on Google ads but did not purchase anything, inflating the cost of running ads without increasing revenue for those running them. Similar schemes would work for Facebook and others).
I'd hope it didn't come to that, but if companies can act without a moral compass, I don't see why the general population has to act any better.
I think you're sending the clear message to the wrong party. It's the politicians you should be lobbying to tax companies on their real global profits, ignoring offshore shenanigans. I'm sure some corporate lobbyists lobby the opposite so we the people need to counter that.
I don't think so. The important point is to get it discussed in the media. It's the media which acts as the main arbiter for public discourse. Politicians are more or less free to act as they wish so long as the media does not amplify the voice of dissenters. Actions which bring the voice of the people into the mainstream media are of use in bringing about change. Hopefully this public discourse can happen through debate alone, but if a legal but questionable method like a botnet that targets corporate greed is required to get the debate going (and/or provide impetus for change), then so be it.
