I think the big change is that companies are now hiring more or less directly 1:1 (often with a employer of record for convenience). Previously companies contracted with outsourcing firms and had no real say over the quality of individuals. At least in my narrow experience the new model works well - there are great people in India, Pakistan, Kenya and Nigeria etc. who are just as good as on-site people and can probably live very well on their salary compared to local living costs.
