The grunts in the field need to have a lot to backup any claims that company x will screw their organization over. If they don't have a solid laundry list of examples, it will never get past the 'steak and strippers' sales pitch.
By making this public the could save many, many, companies from being dependent on technology that oracle has crippled.
So, I don't know who's getting screwed here, but I'm siding with Oracle.
I wonder how would you feel to pay somebody full time for years to work on a project and then, when they leave your company, they fork the project and try their best to alienate all your users. Now, I've heard of burning bridges, but this takes it to a whole new level. If you think about it now, what exactly did Sun pay for when Kohsuke was working as an employee on Hudson? Apparently nothing.
Hudson cannot "lose" its plugins right now because there are no signifiant API/ABI changes between the two forks.
Also, I wonder how much these plugins are actually used? I've only installed mercurial on my servers and I'm pretty sure that will continue to be supported on any fork. As for the rest, as long as they are open-source they can always be forked too.
It's getting a bit tiresome to watch this unfold -- can't the new Jenkins community just go on with their life and make their fork as good as they can? They got what they wanted -- why the constant need to somehow prove something to Oracle?
Having such a big face-less enemy is the best thing that happened to this community as it gaves them something to bond against. I'm curios what will happen when the rush is gone.
