The place I work for hasn't fully embraced remote for in house staff, since lockdowns it's now 2 days a month in the office but we have hired an agency to help with an app rebuild. We've got 5-6 people from the agency working from Spain, Hungary, Poland and the UK and they're brilliant. Really knowledgable about our specific niche with loads of experience in related areas. I have no idea how we'd find people this good in the UK let alone ones tied to commute distance of the office.

I can only assume the huge companies like Meta are wanting to reduce HR overhead of dealing with different countries and states employment laws, taxes etc.

Larger companies have economies of scale that enable dealing with these laws easier.

Smaller companies have to use something like Deel.

That hypothesis doesn't sound that convincing - especially since multiple Americans I know who wanted to join big companies pre-pandemic did so because of the access to living in different places outside of America.
