Let's be clear first. Ottomans ≠ Modern Türks

One of the main groups Ottomans used to reinforce their power in the Balkans was indeed Muslim Gheg Albanians.

This allowed these Albanians, by their conversion, to get a more comfortable life and to grow in number. Ottomans did that to get a stronger grip on the western Balkans, using Ottoman Albanians to control Sandjak, Western Macedonia and Kosovo + the Christian population which lived there. 

By doing that on the other hand, Albanians lost a lot regarding education, teaching of their own language and emergence of their nationalism/revival period.
