Sygic broke trust like that with me . The software is/was excellent and very reasonable, so I bought licences for parts of world and suddenly they made it subscription based app, with ability to keep forever licence for only part of world you bought.
So even though I have fully paid software , i have to pay subscription for the feature of Android Auto and world maps.
It was the list betrayal of trust i have seen. I never used sygic after that at all.
