that is their leading allegation. the company is overvalued because they say so. (and stocks always trade on fundamentals)
going down the long list of "allegations" every single one is normal business practice for any wealthy individual or large corporation. they own a lot of corporate entities in different jurisdictions and have been accused (but never found guilty of) money laundering and tax evasion. not exactly earth shattering stuff.
i don't know anything about this company, but this report has no substance, and coming from what is essentially a no-name blogger with no significant position to trade on, it is not unreasonable to wonder why reuters, nyt, and bloomberg would be trying to give this credibility.
bloomberg has still never withdrawn their totally fabricated story about supermicro https://www.bloomberg.com/news/features/2018-10-04/the-big-h... https://www.bloomberg.com/features/2021-supermicro/ https://www.servethehome.com/investigating-implausible-bloom... that story tanked supermicro's stock by 40% at the time, but they are up 500% since then, so obviously that was not a winner.
