Hi James and Jean :)
Skalfa has apparently partnered with Oxwall. This was done i believe to give them some professional options regarding doing business in the USA since Skalfa is based in the USA and sharing some internal responsibilities.
However they are still two separate entities on the product side of things. An upgrade or feature with one does not necessarily mean an update or feature for the other. One is a specialty software for dating and the other is an open source project. The two can be very different but have the same core at their base. So being part of or associated with Skalfa, Oxwall can still exist as a non-profit foundation under the same umbrella.
Im not an attorney and not giving legal statute however it can be structured this way and has been done not only with some of my old companies but also in the corp world in general. Lots of major companies have within them a non-profit faction which operates independently within. They have their own rules, thier own business plan, their own tax structure and all of that.
The bottom line is that Skalfa does not perform code updates on Oxwall. The Oxwall team works on Oxwall and the SkaDate team works on Skadate. They may have some administrative shared responsibilities such as when someone is sick or on vacation but they are assigned to two different entities.
Its much the same way that Ford set up Lincoln and Mercury. You have seen ads for Ford-Lincoln-Mercury. But Lincoln and Mercury run independent of Ford. You dont see 2016 Ford Mercury or 2016 Ford Lincoln, you just see 2016 Mercury and 2016 Lincoln.
With regards to the images on their marketing page, again im no attorney and one should seek an attorney if questions exist. However, as i understand it from doing some reading on this, as long as Skalfa does not specifically place an endorsement of any kind on that page indicating that anyone of those people endorse them, then it is no different than seeing the picture on google.
Now it could be alittle stretch there on the Jolie one because they could be indicating that Jolie has a profile. However, a profile where? It does not say with them, its just a profile somewhere on the net. So again as i understand it as long as its just a picture and is not actually endorsing anything, i would guess it was safe to do so.
With regards to the core features, remember that Oxwall is just a core with a few base plugins in the box. Anything else you need would have to come from a third party plugin. Some of those features you mentioned above actually could be added to the core at a later date, however that is totally up to the team as to where, when, and if they do so.
I think maybe alot of people might compare Oxwall with paid scripts in which paid scripts surely do have more base features.
Also please remember than the more that is in the core, the more that has to be supported and fixed if broken. That means manpower and talent which is expensive. So i like the idea of puting together a fund raiser to do this and send it off to the Oxwall GitHub when done. Honestly this is probably the best way to get what you need in the short term.
I hope that helps :)
