有人是这样解释的

The US revoking TSMC’s China chip waivers closes critical loopholes that allowed Beijing to exploit American tech while undermining domestic manufacturing. This isn’t about “trade wars” — it’s about ending the globalist scam where foreign firms get privileged access to US equipment while Washington lets China drain our IP. The Biden admin’s 2023 exemptions were a surrender to corporate lobbyists, letting Samsung and SK Hynix funnel advanced nodes to Chinese fabs. Trump’s Commerce Department is finally enforcing reciprocity: if US companies face export bans, so should foreign rivals. China’s DRAM/NAND expansion via CXMT/YMTC depends on stolen tech — cutting their equipment lifeline forces real competition, not taxpayer-subsidized espionage.
