There will be no more Real Estate Sites.
thats not entirely true daniel - there is a verygood GPL real estate software called CMS Realty
its a bridge for joomla and open realty - (although open realty is not GPL)
And on the topic.
like andy said - its not only disrespectful that these devs have left users and joomla alone, its also bad business practice, all the users that paid there subscriptions should be entitled to what they paid for
thats support and updates/bug fixes
i personally feel that joomla will come through this and in some months time we'll all be saying
"man that wasnt as bad as i thought it was gunna be"
there are always more devs primed and ready to take there place, its just a matter of waiting, till the storm blows over
the thing is - anyone who knows how and wants to - can create anything for joomla that they want
they dont have to release it - either free or paid - does that mean there breaking the rules of GPL
as there software is not GPL - i highly doubt it - and anyways who would know?
