Yes, but (importantly) degrees vary. The politics of working for an adviser chasing tenure are different from, say, running a SaaS, writing an ebook, or selling a plugin.
You mean, politic is different if you're not working for anyone? I can't even agree with that. You will still have politic in place if you have people working for you, or if you have critics reviewing your ebook, or if you're trying to get your plugin accepted in a store, etc...
