via The Bold Italic(which is now also a medium blog…the good ones keep switching to this for-profit platform):

However, City CarShare was recently bought by a corporation, Getaround. And Getaround built its platform on top of Facebook. So when I went to migrate my account over to them, I found that there’s literally no way to do it as a non-Facebook user. If I want to share cars with my fellow city dwellers, I’m compelled to strike a Faustian bargain.

To access the services of Getaround, one must authenticate their identity through Facebook.

I was a City-Car-Share member while in SF. Requiring me to authenticate a Facebook account to use a service is just as bad as giving over your blog to Medium’s Terms of Service. You can’t rally about an Open Internet when your blog is powered by Medium.
