this is somewhat misleading, although the copyright holder may always
distribute their works under another license, they cannot retroactivly
change the license on previous releases. once something is gpl'ed it
always is. the author may also release it under other licenses, but the
gpled version is no less valid because of it. the author may also keep
future releases private but the previous GPL'ed releases can still be
built upon by the comunity. GHC (or whatever) is not in any danger of
disapearing. even if they  wanted to close it, they could not take back
the previous free version and it could become the seed for a open-source
