I understand the complaint from console players, but it's wrong to refer to "the lack of UI customization in this game, especially on console". There is no lack of UI customisation on PC, and its absence on console is purely down to the failure of the console providers to permit the use of addons. Hence a more accurate complaint would refer to "the lack of UI customization in this game on console due to the console providers' unwillingness to permit it".
And yes, as it happens I do play on PC and don't feel the need for any addons, preferring a simplistic UI and with no desire at all for a mini map, but for those who do want such features then they are available, but console players need to lobby their console provider rather than ZOS if they wish them to be made available on their platform. If addons were permitted on console then I've no doubt there would be plenty of console players providing them, but meanwhile there's less reason for ZOS to integrate the mini map addons into the base game than there is to integrate the trading addons which are even more critical given the present trading system but which are also denied to console players.
If I had to guess it would be more to do with ZOS does not think that adding a mini map is worth the effort and choose to spend its resources elsewhere.
