Florian finds GNOME a great community that welcomed him with open arms (once he dared to make the jump). He found some real friends over time.
There is also the mission. Providing a computing platform that is driven by vision and need rather than monetization opportunities and a strive for market domination is as important as it ever was.
Last but not least, when GNOME builds an OS "for everyone", that includes him. When GNOME gets better, so does his computing experience.
