Because the pandemic is forcing literally _everybody_ to work their tails off to figure out how to make remote work succeed. Once managers master that (and they will because they have no choice), it's a tiny, tiny jump to offshoring.
Are you talking about hiring professional software engineers full-time from other countries? I think that is actually plausible and I've seen it work at multiple companies. Buying services from a "offsourcing" shop on the other hand - always a complete disaster or literally more time managing them than to build it yourself.
