If you don't like Facebook's actions then don't use it. Having open speech on Facebook's platform is not an inalienable right. I don't agree with Facebook's privacy policies and thus have deleted my account and use other platforms. This isn't difficult. This article is tantamount to saying "Woe is me, NYT won't publish my op-ed." and expecting anyone to take you seriously.
I fail to understand why is this a 'problem'. FB can do as they please (fail or succeed as a consequence), they aren't a tax payer funded institution answerable to the public at large.
In effect, people are dictating how FB should 'run their business'.
