Well, I know that none to whom I have installed GNU/Linux would not use it if
they would have to stop using Flash.
Everyone using Flash does not solve the flash problem, but everyone using MS
so that they can use Flash does not help a bit people to migrate to
GNU/Linux.
So you have two choises: a very bad choise and less bad choise. The very bad
choise does not include anything good. It is completely and totally bad. The
less bad choise includes something good. People can begin to learn to see
that MS is not the only choise, and more demand for GNU/Linux support can
come.
In Finland broadcasting companies use Silverlight in their websites for
streaming video. The national broadcasting company YLE (similar to BBC in
England) and one other company does not. There is also a company who rents
movies by using Silverlight. None of those work with Moonlight, and thanks of
your link, now I can lose officially my hope in that they ever would.
Anyway, I may try to solve broadcasting etc. flash/silverlight problems by
buying almost the same content and much better service from one awesome
company in Finland who supports Free Software. I never watch TV, but my wife
does, and I can't be horrible dictator saying that this policy prohibits you
from doing what you want to do.
Regarding Skype, her relatives use it with her, but I managed to get her
mother and her to try google talk/video (which needed some sort of
proprieatary plugin). I wished they would had begun to use that because then
I could had guided my wife to use Empathy/Pidgin. They did not, and one thing
is quite sure: her 75 year old grandfather and 80 years old grandmother does
not begin to use anything else than Skype since they have learned it.
It sucks, but there is not much what you can do before becoming an asshole.
Free Software is good and important but better still not become an asshole
but rather let people have freedoms they want in a same way you want freedom.
If the "freedom" is forced upon them by you, then there is not much
difference between you and those who try to take the freedom away from you.
