Synergy is a terrible model for supporting open-source projects. While the project is very useful, the lead devs basically begged the community for years trying to support full time developers on what honestly started as a very small tool (although the compatibility issues are many). They made to pay to put in bug reports or vote on which issues were important to you. The devs eventually got a bunch of donation money and then they wasted it all on an office and full-time employees with zero revenue. After using community donation money as seed funding for their new business, they decided to start charging for the installers. They also removed resources that aided distribution in an effort to get more people to pay them. There are tons of open source projects that dwarf synergy both in scope and lack of funding, yet synergy somehow needs thousands of dollars, over and over. In my opinion, they are trying as hard as it can to close down the GPL project so they can make even more money.
