Cypriots were enslaved for ever in the past. Where did you dig that up from?
During pre Roman and post Roman periods they were part of the ruling empire of the day, ie Greek and Byzantine. The ascendance of other empires that captured Cyprus also captured the surrounding countries, and more sometimes. Cypriots were not the only enslaved people in the area. Search out the origins of the word slave. Would you regard Russians as habitual slaves because at one time Russia was the source of slaves?
The former colonies of European nations should have hung their heads and accept their fate, if they followed your recommendations. Today they are independent nations- the USA being the most obvious example followed by nations of South America, Africa, India and South East Asia.
As for emigration, thousands of Cypriots moving etc, what the hell do you think the Anglosaxons did to populate Australia, Canada, N.Zealand and the USA? Obviously they did not stay home. Italy gave 20 million people to the USA. By your criteria that justifies the remaining Italians losing Italy.
Are you the man from Xeros? You sure have changed since the last time i came across your posts on this forum. Something is wrong.
