In general corperations don't invent products
You have a marxist view of innovation. Hint: you also confuse it with funding, which is, itself, marxist. While I accept that there is a cost to innovation [invention, if you will], it certainly is not the government that is the braintrust of innovation. Nor does government truly produce anything, even in marxism, just because government owns business in that economic model does not mean that government is the new idea generator. If it were, we'd have far less issues in business just because of the intervention of government in business. There's a reason why the Constitution's Article I, section 8, granting powers to Congress, has little documented involvement of Congress in private enterprise. Not saying the government abides by the limitations, because they don't. There's just no constitutional justification for their involvement in private enterprise. Please try to understand the distinction between innovation and funding. The proof? If government is the braintrust of private enterprise innovation, why don't they already have the expertise they claim they need to investigate for legislative purpose; the ONLY reason why Congress should investigate anything other than impeachment of a federal officer?
By the way, by Supreme Court precedent, Congress is supposed to announce their legislative purpose for any investigation they conduce, other than for impeachment, but they don't even do that. Tell me, what is the specific legislative purpose Congress has announced for the January 6 investigation?
