Ask HN: What are we doing about Facebook, Google, and the closed internet?
Make your website of record your website.  Make social media platforms and others (e.g. Google) secondary to that.  Don't let Google and Facebook control how you build your website.  I am amazed at companies that take their websites and subjugate them to their Facebook page.  You may gain social attention but you are handing over control.  Never, ever, ever say to contact me go to facebook.com/xxxx or my email address is xxx@gmail.com.  Your site is yoursite.com and your email is youremail.com.  Your login to the sites you build are email addresses, not tied to social media providers.  The closed internet providers are enhancements to your sites.  They do not take the place of your site.  If you follow this philosophy, you are supporting the open internet.  Own your .com.  Don't let others own you by taking that from you.
