Ask HN: How can people with ties to anti-privacy software switch to FOSS?

Many of us use social media and other online services significantly in our lives. Many of us are FOSS/privacy advocates who have made the difficult switch to only using such software. Some of us (including myself) are somewhere in between. We know the benefits of reducing our links to privacy-disrespecting companies, but we are tied to using such services because of work or ease-of-use or some other reason. How can we make the great leap in an easy and (mostly non-disruptuve) manner?
