"But not overnight, or in a week or any other period of time in which business cannot theoretically continue day to day operations."

Understood ,Sometimes business are in this precarious position due to bad planning and sometimes they simply have no choice due to the specialized nature of what service they offer

I have witnessed both scenarios in my former Career in the Design& printing business in the Washington DC Metro Area.

I worked for a large Format company where the specialized 

printer driver, required to interpret the postscript Data, to our 10 foot wide roll to roll printer.

was being coded and updated by ONE independant contractor

who was not a direct Employee of the machines manufacturer

Whenever there was a firmware update to the hardware of our

giant printer( which was often)

we could not print with it until  "that guy at home in his pajamas"

got around coding us a new Driver.

That company made a bad choice in going with this manufacture.

I left to work for a Rival large format company shortly before my former Employer went under.

Strangely Enough, My new Employer was in the process of upgrading to a grand format,10 foot wide printer and was about to buy a similar Device that used the same single source " guy at home in his pajamas" printer driver.

I warned the owner (my new boss)

 ,in  severest terms, not to do this

and we went with a Canadian Company Called "Gandinnovations" instead.

My point with this story is that it is up to business owners to make forward looking decisions as best they can  about platforms and software trends to minimize the disruption 

of the ever changing technology landscape.

I certainly do not want the government dictating  who can have a proprietary format or sell their graphic software business to another company.

BEST WISHES.
