I also like and run NextCloud, it is the "cloud" back-end for my entire family. That said, it seems to me that this means that OwnCloud en NextCloud are now truly diverging and OwnCloud is not just a less feature rich version of NextCloud. I think it is very interesting to see what happens to OwnCloud now. I mean, imagine OpenOffice being rewritten with different technologies from LibreOffice... I'd be interested once again!
