I've never heard stuff like that on xda-developers where most of the roms
are pirated or contain some not distributable files or are downloaded from
megaupload.... and nonetheless they work and in fact they work better most
of the time and when they don't people are willing to help despite flaming
you for posting in devel section rather than in the questions section.
The only responsibile for this situation is Nokia as they have the possibility
to distribute bugfixes to people as their distro is deb based but choose not
to do so and drive users with not working phones to the insanity of flashing
dubious ROMs to get their expensive toys working as expected finally.

P.S.: all this resembles to what happened in the overclock thread where
maemo-nokia people were telling for months that it was impossible
to overclock the N900 and that all sorts of bad things would happen
until it was proved that it was possible with no nuclear fallout.
