To be honest, I may not have the best answer for this. One thing to consider is that there is no ethical consumption under capitalism, and that boycotting products, companies, and individuals is not going to solve the problem of capitalism and its symptoms. We have to do what we can to survive. I am not going to condemn people who still want to use Hyprland. In a socialist society, I believe my earlier statement would be applicable. However, I would consider the open source community as antagonistic to the capitalist system, and it is a part of our society that is need of rooting out its reactionary elements where possible and most effective. Just as a party needs to have its members accountable for their reactionary actions, the open source community must collectively do likewise. I believe FDO made the appropriate choice of removing this individual from their community. I believe the Hyprland project may likely suffer through this alone as the dev cannot contribute to the important projects Hyprland depends on. People using Hyprland don't need to immediately abandon it for now, but I suspect a fork of Hyprland with a better team may be necessary at some point in the future depending on if and how the original project devolves.

PolyMC's hostile takeover lead to the fork of Prism Launcher, which has become the surviving project as the majority of devs were kicked out and moved to the new project. In the case of Hyprland, a protest fork would require a separate team dedicated to the project, which of course would be less certain to succeed, but may be feasible as it isn't a large project such as the Linux kernel.

I believe efforts to such a fork would be beneficial, but resolving these issues with forks to isolate from reactionary devs will not actually solve the actual source of the problem, which is the far-right propaganda, media, culture, etc. enabled and enforced by capitalism. So yes, exclusion of reactionaries is a band-aid solution (sometimes more harmful than helpful in some cases), and people should use the tools that help them survive in this capitalist society. I just personally like to boycott some of the most abusive and dangerous companies and individuals when I can, and I believe we should condemn reactionaries for dangerous and bigoted behavior (and have them face the consequences of their actions) as it important for unifying the working class and protecting minorities. We need to root out racism, sexism, etc. as it inhibits the working class from working together and realizing their true enemy.
