I have been using them fairly heavily and I have not noticed much of a ammo issue, but I also cycle my weapons now more than I used to. I am constantly switching between weapons. Granted I tend to use a sidearm when I am not using a handcannon if not doubling down and using both. I find with the more frequent heavy drops I end up using my sword to break down the tough enemies and use sidearm or hand cannon for the tier one or weakened tier two enemies. Also the new supers leverage a lot of kills that don't require ammo. It isn't to say that there isn't merit to how the issue feels especially on the back end of everyone just steam rolling through content with the Fate bringer and Exotic handcannons, but I honestly feel there is a much better feel of diverse weapons play than the game originally supported. Also situational awareness goes a long way if you make sure you aren't picking up the white boxes when you are almost full and shorting yourself on ammo. Considering it seems that they buffed the amount each white ammo box returns. Last aside... the green special ammo boxes in strikes also return primary ammo. I am sure I will get flamed for my well written opinion, but hey that's what I get when I jump on a forum thread where everyone is already decided on the answer of the question since the slanting of the question supports their feels.
