The direct testimony of a couple of TSMC chairpeople is “I’m a Christian and I believe in God. I see God in nature, yes.”
Pretty much all Christians see god in nature. They’re Christians.
Zero evidence that they specifically hire Christians. Zero evidence that they push religion onto people.
You’re the one extrapolating that all of TSMC must be fervently Christian (not backed up by the article!), and that Taiwan in general is Christian in culture (definitely not in the article!)
I also highly doubt that the culture issue here is that Taiwan (3.9% Christian) is too culturally Christian for the US (67% Christian).
