what exactly is the rest of the world’s excuse for not creating viable local or collaborative alternatives to American corporate services and products?
Decades of American diplomacy and big tech market domination hindering them from doing exactly that. It's not a coincidence all relevant tech companies are in the US. For the most time, if you started a company elsewhere and it became reasonably relevant, you had to eventually move to the US or go down.
Of course, you could start a non profit, but it would also stay irrelevant because it's incompatible with big tech. Microsoft's docx, android and iOS locks etc.
That said, there is now a political opportunity to move away from this system, but it takes a few years.
