The maintainer will fork the project under a new name, and continue to work for it. GNU will be left with a piece of software that slowly bitrots and becomes outdated, unless it can attract someone else to take it over.
Would you care to contribute something beyond what was discussed in the article? Do you also think gnuplot and Gnutella should change their names? Given that Nikos controls the gnutls.org domain, should be obligated to turn control over to gnu? For free, or can he charge them for the transfer?
They had someone, who seemed to be doing a good enough job. Now they have to find someone else to do that job, while competing with a new fork of the code.
And the cost of obsolete code is not a bit of web storage; it reflects on the project as a whole. The GNU userland tools have been important for Linux. But what happens if people move to different user land tools?
It's not super important, but it is a shame that people leave projects.
Perhaps if free software and open source software had invested in a bunch of diplomats to translate the flames between De Raadt, Torvalds, Stallman, etc things would look very different today.
