The product, in this case software, normally had such and such a feature included in the main software. As more requests for expanded functionality occurred, the decision was made to take that feature OUT of the main software, make it an "add-on" and so you pay for the software and the add-on.

Now the decision is to take the add-on, divide it in two, make two add-ons and the cost for those two add-ons together is more than the add-on was before (with no additional added functionality).

So it's gone from Software with the feature included => Software + feature as an add-on => Software + two add-ons to get the feature.

It's interesting to me.
