Michigan Bans Flavored E Cigarettes

See above.

They can't corner the custom vaporizer market and guarantee long-term, repeat consumption if folks are to control their own nicotine intake (or eschew nicotine together) and are able to buy customized vape liquid from Mom and Pop vendors or make it themselves.

One can buy and use a liquid vaporizer for years and never put a dime in Big Tobacco's pockets and never, ever become addicted to nicotine.
That's not good news for the future of Big Tobacco.

I said almost 100% of the market.  The fact is that most vaporizer products purchased contain nicotine, once they are addicted they will continue to use the nicotine containing vaporizers.    Just because some people will avoid purchasing from a tobacco company does not mean that most will.  Also, it seems that non nicotine containing products may not be physically addictive but they seem to be addictive psychologically.  

The tobacco companies are lobbying against vaporizing laws in general and why wouldn't they make non nicotine products that are cheaper than a mom and pop shop?  I believe they will, they have no reason not to.  They are about making money the how is inconsequential.

The tobacco industry's customer base continuously dies off in large numbers. Chemical addiction (to nicotine) is necessary to ensure that replacement consumers stay dependent on Big Tobacco's products for the duration and allows the industry to maintain it's profit margins. That's why tobacco has been genetically engineered to contain more nicotine and why BT formulates their products to ensure maximum delivery of said addictive substance. Many of the major e-cig brands contain more nicotine than cigarettes and most of the e-cigs they offer require purchasing an entirely new unit/set up for folks wishing to "step down" their nicotine levels.

They need people hooked. Chemically hooked.

There are plenty of consumers who resent these tactics, myself included, and would rather not feed the Big Tobacco beast at all. I've also noted that most of the non or nominally-addicted recreational vapers I know will not knowingly purchase from BT because they simply do not trust the industry to properly disclose nicotine levels and/or are opposed to the industry in general ethical terms.

So yes, I think that the ability for vaporizer users to customize the amount of nicotine themselves and use little or none is deeply problematic for the industry. 
It can't replace the revenue lost by the deaths of half a million addicted consumers every year with a growing number of non or nominally-addicted people have no need or motivation to be product loyal.

If younger generations choose vaping as the Premier Pointless and Utterly Stupid Habit over smoking, then the tobacco industry could conceivably be screwed within a decade or so. It would undoubtedly still exist, but it would be greatly diminished from what is today in terms of revenue and political influence.
