My own site runs on open source software and I am part of the #IndieWeb movement, more information about that at https://indieweb.org
Earlier this year I posted about my move away from silos with my #FacebookFreeFebruary. That is documented along with other “silo-quits” at https://indieweb.org/silo-quits#Ken_Bauer
Humanity has been contemptuously used by vast digital empires. Thus it is now necessary to replace these empires with decentralized networks of independent individuals, as in the first decades of the Internet. As our participation has been voluntary, no one doubts our right to take this step. But if we are to persuade as many people as possible to join together and make reformed networks possible, we should declare our reasons for wanting to replace the old.
