Corporations are made of people and you do not lose your rights because you form a corporation.

That doesn't answer the question. Do corporations have the right to bear arms separate to the rights of the members of the corp - can Google keep an arsenal even if none of the people in it had a gun license?

Knowledge of where Microsoft forgot to enable a security check is not “bearing arms”.

Imagine that world. I point out a mistake to you, and by reading or hearing it, you are suddenly holding a gun! We would have to criminalize coredumps :)

No corporations aren't people. That headline is pure clickbait. Some rights are extended to corporations due to corporations being a group of people who come together for a purpose.
