do your own homework

If the EU commission doesn't want to give money to IBM/RH for FOSS maintenance, then there's SUSE as a European option. I haven't really followed SUSE, but going from wiki they don't seem to do that well, with them being acquired over and over and then ultimately being delisted from the stock exchange due to doing so badly.

In any case, be it SUSE or something else, some kind of umbrella organization is probably needed for this kind of maintenance effort. It doesn't seem sensible that some individual maintainer of shadow-utils or whatever needs to write an application, multiplied by every small but still critical project.
