>> Have the executive block things pretty much arbitrarily undermines the rule-of-law ... If the US wants to block Chinese companies, then pass laws in congress to do so... That's not how the rule-of-law works. The bill of attainder doesn't allow the US gov't to punish an entity (or a group of) arbitrarily by legislating. The legislative and executive branches have already been briefed on privacy and/or security threat Tiktok poses to US. The US senate already passed a bill to ban federal employees from using Tiktok on gov't issued devices, which is exactly what the legislative is supposed to be doing without overreaching and impinging on Americans' civil liberty, and Trump in turn issued executive orders to deter national security/privacy threats from foreign entities. The judicial branch likewise appropriately exercised their power by delaying Trump's EO and challenging his authority. That's precisely how the rule-of-law is supposed to work in the US -- there is nothing novel or arbitrary here.
