Racist is an awfully strong word.

You may not like it, but it's surely just pragmatism on their part. It requires a considering investment in lawyers and time for each country they launch in, so it makes sense to start with their home (and likely largest) market.

last time I checked, the USA has pretty much people from all races.

Most US companies will launch something in English only with the domestic market in mind to test the waters, then when it becomes economically viable to do so expand licensing and other issues out to other countries.

I'm sure the companies that innovate in your country do the same.

Coming from a small nation, doing anything tech-focused and not launching internationally is hard for me to wrap my head around. But I guess the factors in play here are a) a huge domestic market and more significantly b) the inevitable licensing issues that other commenters have pointed out.
