Ask HN: Risks/Disadvantages of Remote Hiring in Developing Countries

The advantages of remote hiring in e.g. India are clear - it's cheaper than in Western countries, and flexible (loose coupling), and whatnot. Therefore, big companies in my country (Austria) have outsourced software development to the Far East, beginning in the 90's.

However, I have noticed a reversal of this trend in the last few years, and I wonder why. Surely there are factors which impact those companies negatively, or else they would stick with their strategy? Like brain drain impacting product quality or something?
