If you are in Europe or any other place than the US, you are basically powerless to American big tech.

Encouraging competition and using software from smaller companies, Chinese or not, is our only chance to level this.

I wouldn't say Europeans are powerless against american companies. Legally speaking, yes, but then so are Americans themselves. The only thing we can do nowadays is public outrage. Doesn't matter who writes the medium blog post, as long as it hits MAJOR_SOCIAL_NETWORK frontpage.

Well, if it is truly open source and has reasonably reproducible builds, I would absolutely use it.

Unfortunately most Chinese suppliers don't take their GPLv2 obligations very serious when it comes to Linux kernel drivers for example. If these new(?) players do, I can only applaud it.

The lack of transparency in who they are isn't really raising my hopes...
