Incorrect, we've invested tons of work not only in RPM, but also in KDE, deprecation of legacy perl tools with migration of python in process, have tons of actual R&D in place (compared to Mageia which has pretty much none as historically all of such was mostly conducted by Mandriva employees), only to mention a few things..
There's also the lesser known, but crucial fact that laid the premise of Mageia, which wasn't actually that all people at Edge-IT was fired (which again has a totally different meaning, implying that they were terminated against their will based on misconduct on their part), only two people in engineering wasn't offered a new contract with Mandriva during the liquidation, one of those were the director of engineering (which obviously wasn't offered a new contract due to any redundancies considering the position..), namely Anne Nicolas, who up untill then had been one of the only two people in the company that opposed the idea of a foundation and effectively blocked it, due to her position as project leader. Most of the other employees declined the new contract offered due to this and decided to go with her in secretly forking the distribution and conducting in what probably could be considered as pretty strong disloyalty and destructive behaviours towards the company to pave the way for when to announce their project.
So Mageia wasn't ever founded based on the fear, distrust and dissatisfaction within the community, but rather about a few individuals who felt it important to remain in control of it (considering how open the cooker community has been, it's not like they'd have any problems doing what they want within the distribution regardless of employment) and creating grounds for creating their own new company, Hupstream..
Due to these facts, the remaining people at Mandriva has in general a very strong distaste for and not particularly willing to be working with, or certainly at least not working with Anne as a project leader again, as her success at Mandriva wasn't really there and the only people actually having good relations with her being some of the people in engineering at Edge-IT and their social circle in Paris, which again formed a cliqué that became the bottleneck of the distribution and community.
One should notice the *complete* lack of ie. Conectiva people who actually went to be involved with Mageia, there's a reason for it..
So this is probably the biggest issue for us to even consider rebasing on Mageia and participating in a project under people they simply don't trust or have any respect left for.
This again of course sounds like pure slander from someone disgruntled from anyone with the bias against Mandriva, consider it whatever you'd like, but for me it's rather about finally stating in public about some truths that never has been brought attention to and that people at "our camp" simply has too much politeness and professionalism to go on nagging about in public, even despite it being well-known within the company.
For collaboration with Mageia, sharing efforts, inviting them to participate in a bigger foundation with serious commercial backing and such would certainly be welcome and to everyone's interest, but it's simply unrealistic and something few of "us" would be willing to accept if it were lead by people one simply doesn't trust.
