Not arguable. Bills of Attainder refer to criminal laws and are specifically to stop government abuses of personal liberty. Corporations don’t have a guaranteed right to consistent laws, otherwise they wouldn’t spend so much on lobbying. The knife cuts both ways.
Huawei has argued that sanctions against their company constitute a bill of attainder.[1] The provision that an executive can have 100% of their income from the company seized, though, is arguably a criminal provision. But looking at the history of bill of attainder cases, this probably won't be considered one. [1] https://sgp.fas.org/crs/misc/LSB10274.pdf
Also, I don't really think the courts would agree with you based on their interpretation of civil forfeiture laws. The only unusual thing in the Huawei case is that it happened to someone with serious money.
