My point isn't that this happened. I don't think anyone did anything other than write and read a blog post. It's that we exist in a world where it could and therefore the thought that I might need to question the authenticity of things is ever present which I find troublesome.
This isn't a modern problem. Shakespeare was paid handsomely by the Crown - hence his somewhat hagiographic biographies.
You will never find writing which is free from bias and influence. You can either make peace with that and find ways to mitigate against it, or you can remain in distress.
