Google any sentence:

One thing that happened last time re exploitation.
The so called fluorocarbon used for refrigeration...
Replaced by a more safe refrigerant that would help the ozone layer.
The fact that DuPont's patent on this manufactured gas was about to
run out was a coincidence of course.
From Wikipedia
The Ozone depletion layer has been increasing, or shown no sign of
recovery of course.

You didn't read the whole Wikipedia article, the recovery is not expected to
take place for some time.

" It is calculated that a CFC molecule takes an average of 15 years to go
from the ground level up to the upper atmosphere, and it can stay there for
about a century, destroying up to one hundred thousand ozone molecules
during that time."

but it is starting

"Since 1981 the United Nations Environment Programme has sponsored a series
of reports on scientific assessment of ozone depletion. The most recent is
from 2007 where satellite measurements have shown the hole in the ozone
layer is recovering and is now the smallest it has been for about a decade"


The year 2008 saw the longest lasting hole on record, which remained
until the end of December.[89] The hole was detected by scientists in
1985[90] and has tended to increase over the years of observation.
The ozone hole is attributed to the emission of chlorofluorocarbons
or CFCs into the atmosphere, which decompose the ozone into other
gases

From Duponts site
DuPont led the industry in the phaseout of CFCs and transition to
environmentally acceptable alternatives. At the time, DuPont
estimated that more than $135 billion of existing equipment in the
United States alone depended on CFCs. In January 1991, DuPont was the
first company to launch a family of refrigerant alternatives that met
performance, safety and environmental criteria and could be used in
existing as well as new equipment, thus minimizing the transition
cost to thousands of businesses and consumers around the world. The
company invested more than $500 million to develop and commercialize
CFC alternatives. CFCs accounted for less than 2 percent of the
company's revenues.
Not from their site, based on suspicion...There is considerable
evidence that the ban on R -12 is based on bogus information and

Please tell me where to find the considerable evidence of the bogus
information or who said that it existed.

orchestrated by Dupont because their patent on Freon was running out.
It's unlikely the decision will ever be reversed but it's just one
more example of how big business is wagging the dog.


It is odd to have DuPont accused of making it all up when they denied it was
happening.

Also from Wikipedia

"The Rowland-Molina hypothesis was strongly disputed by representatives of
the aerosol and halocarbon industries. The Chair of the Board of DuPont was
quoted as saying that ozone depletion theory is "a science fiction tale...a
load of rubbish...utter nonsense"."



If the link between CFCs and ozone depletion were all phantom why did so
many countries sign the Montreal agreement? Are you saying all their
scientists were under the thumb of big business?

Also from Wikipedia

"At Montreal, the participants agreed to freeze production of CFCs at 1986
levels and to reduce production by 50% by 1999. After a series of scientific
expeditions to the Antarctic produced convincing evidence that the ozone
hole was indeed caused by chlorine and bromine from manmade organohalogens,
the Montreal Protocol was strengthened at a 1990 meeting in London."

As with the previous case I would be interested to know where you found this
conspiracy theory.
