For those who claimed Chinese cash is toxic, let me ask you an important question: what about Softbank's cash that primarily coming from Saudi? What about the Ivy League schools' endowment money donated by "morally unethical"(including but not limited to middle east) sources? Are you not going to send your children to Ivy League schools?
Rather, the claim of toxicity stems from the perceived tendency for Chinese investors to be difficult LPs and steal intellectual property both pre-deal during diligence and post-deal once they are in the capital structure. There's an additional perception of 'toxicity' in terms of the way that having Chinese investors might limit a company's ability to procure US Gov contracts, which is getting tighter under this administration, as described in the article.
The comparison to sending your kid to an Ivy League school makes no sense to me whatsoever, seems like a total non-sequitur.
