Yes! So much this! You can choose your email provider, or your cell phone carrier, and no matter who you choose, you'll still be able to email and text/call others (regardless of who _they_ choose). But you can't choose a new Facebook provider. There's no recourse if a given platform is behaving badly, and the network effect just reinforces their hold on users. Open protocols free users to make choices about providers and foster competition based on the service provided instead of having to "choose" to go where the people already are.
