IMO it's even worse than that. Not only do we expect corporations to do the government's job, we're also giving corporations more power than we give governments.
Just look at the "it's a private company they can censor whoever they want!" crowd. They actually believe companies who control over half the content we're exposed to online should be able to censor and deplatform whoever they want for whatever reason they want.
I visit Canadian subreddits and they cheer when our telecom oligopoly censors RT news and unironically ask to "do fox news now!"
