Perhaps there should be an exception when the file name matches the SHA-256 sum of the file contents. This would give you assurances that the file was not modified in transit while giving you the promptness of unsecured HTTP.

Personally, I don't think corporations should pay ANY taxes.

Every cent of profit that a company makes will either,

1) Be reinvested

2) or show up as come sort of income on some individual's tax return.

It has long been known that corporations use all sorts of foreign tax shelters and other creative tricks to reduce their tax bill. The tax code is too complicated to try to close all the loopholes and do it faster then they lobby for new ones. All the current system does is drive money overseas. They don't and won't pay taxes anyway.

Don't tax the company, tax the dividend recipient. An individual's taxes, while sometimes quite complicated, are far simpler and allow for fewer loopholes. Disclaimer: I am employed by GE (as a bottom-of-the-food-chain factory throng with no connection to this).
