The answer to fewer transplants question is yes, those drugs will result in fewer liver. transplants. The numbers of transplants haven't gone down much yet, because these drugs have been on the market for only a few years. The natural history of HCV from infection to transplant is several decades, sometimes many decades
After initial infection with HCV about 85% of infected people become chronically infected and about 15% manage to defeat the virus at the outset and are either cured or their disease is at such a very low level that there is no functional difference from being cured.
Your mother is very likely one of these lucky 15%. They have antibodies to HCV but have little or no detectable virus in their blood, and their liver enzymes stay normal. They will not need the new HCV drugs nor are they likely to ever need a liver transplant.
Of the 85% who become chronically infected, if they are not treated and cured, many progress over a period of years to increasing levels of virus in the blood and liver, accompanied with rising levels of liver enzymes indicating liver damage. Ultimately when the liver becomes so damaged by the virus that cirrhosis and liver failure sets in, and a transplant is the only hope.
The new drugs can cure the virus before the liver damage gets too great, and thus the need for a transplant goes away. As the years go by we will be seeing fewer and liver transplants due to HCV infection. And the first data showing this effect is starting to come out. The need for transplants is starting drop. This trend will continue and accelerate as the use of the new drugs expands and more and more people are cured of the HCV:

I don't doubt that alcohol and certain drugs can also damage the liver. No one questions that excessive use of alcohol can wreck your liver. That's been known for centuries. And it makes sense that HCV and alcohol working together could make your liver sicker even faster. But there are plenty of clean-living non-drinkers who get HCV through blood transfusions and who progress to severe cirrhosis and liver failure. Alcohol can speed the process up, but HCV is perfectly capable of destroying your liver all by itself.
The Hep C "hoax" thing is typical conspiracy theory nonsense. The existence of Hep C has been well established for long time. No mainstream medical scientist or doctor doubts it. But there is no point with trying argue directly with the true believers. For them it has become a religion. One can only hope to limit the damage they do to innocent patients who fall prey to their story.
The same thing happened back in the 80s and 90s with HIV/AIDS. Peter Duesberg, a prominent professor at Berkeley, came up with a similar conspiracy theory that the HIV virus was harmless and didn't cause AIDS. He blamed the failure of the immune system in AIDS on excessive drug use (sound familiar?). His irresponsible theory cost countless lives. There were some prominent, outspoken parents who embraced his theories and publicly stopped anti-HIV therapy for their kids. And the kids eventually died of course. But being true believers, the parents could not bring themselves to admit they (and Peter Duesberg) were wrong and had cost their children their lives.
And the country of South Africa became heavily ravaged by AIDS when its then president, Thabo Mbeki, bought into the Duesberg theory and stopped government spending on HIV treatment and prevention measures. The result - millions of out of control cases of HIV/AIDS. Thousands and thousands have died of it. And today a full 10% of the entire population of South Africa is infected with HIV, and the government is struggling to get ahead of the epidemic.
We don't need another round of tragic nonsense like that, and this blogger guy is not helping.
