If your argument is that gov't should never subsidize a business, I think history says otherwise. The Internet was born of an DARPA project. If your point is that some businesses can't stand on their own without a subsidy, we're in agreement.
The real question is when does it make sense for the gov't to subsidize an industry? A book could be written on that subject. As a reminder, oil and gas still gets billions in subsidizes. In my business it's well known that O&G drilling partnerships are a fantastic tax avoidance strategy.
-- I totally agree with the majority of what you wrote here. Just want to get it straight. What I wrote is not true?
Well , gov led incentives are not ever a good sign that any business is strong enough to stand on it's own.
-- I have NO argument here? Will admit to several grating
boomer attitudes...

like a scrape against a chalkboard.
But, even when I talk about the poor, less than expected EV sales and such, I am not a protesting anti EV person. The technology interests me greatly and I hope it can be improved with leaps and bounds quickly. Regardless if I plan to own one, I do not at this time for several reasons. Does that place me at odds or in some fight with EV fans, supporters or owners. It should not. I certainly don't plan to own a yacht either.
-- History can say whatever it wants. It says a lot and I am not saying history is a liar. So , mistakes have happened thru history. A lot of good has happened too. Maybe we should at least try to avoid the same type of things with similar poor results. I bet you know the definition of insanity about doing the same things repeatedly yet expecting different results. Most of us have done it. Me too.
-- IMHO oil & gas should get ZERO from any gov since they make so much profits. A check of the stock markets can prove what they like to deny about profits. All we need to do is look at the leaders of Middle East countries swimming in wealth from oil monies.
-- I can still feel it is simply not a good an idea for the success of any type of business to be too dependent on anyone but it's very own customer base. Is a company that is able to build up, become known , rise up thru exposure to the masses in order to sell a product or service but then continually struggles to move the product weak? or maybe even here at the wrong time for one reason or another? Is that an indication that something? anything? is not working or clicking right with the main target customers? Probably is. What else could it be? Products , plus their future maintenance can be so costly to the point that it eliminates a great majority of potential customers. There are hosts of reasons everyone does not buy all the same things. Is it good that a company may even need laws to be changed to basically eliminate competition and to force customers to their very own product?
-- There so many stories about several companies who in the past several years needed incentives and much money from the gov. Great things were promised to us from the use of that money. There are (21) Green Energy companies reported on that took millions (likely billions total) from the gov since 2010. The only thing all (21) companies accomplished was to take tax dollars, then very quickly all proceeded to shut down and file for bankruptcy protections. Seems like a very similar/strange pattern with all of them doing exactly the same. I would not say Conspiracy. No, the word most likely should be Theft. I say they should all be defending themselves for theft in courts across the USA today. Plus there should be huge investigations into where all those many millions went to so quickly. It just seems like nearly every time a business needs tax monies from us, our gov to survive, things often do not turn out well or to the advantage of the providers of that money.
