I have absolutely no idea what the question asks. Therefore, I look forward to reading analysis of the exact meaning of question 'What percentage of 75-year-olds and older have NOT been using the internet between 2012 and 2015".

Percentage of people 75 and older who do NOT use the internet has decreased from 66% in 2012 to 50% in 2015

=> Among the people having age ≥ 75 yrs, 66% did not use the internet in 2012 and 50% did not use the internet in 2015

Thus, assuming 100 people having age ≥ 75 yrs in 2012: 66 do NOT use the internet ------- this is fine

But now, how many people would be there having age ≥ 75 yrs in 2015? Obviously it will not be the same as in 2012 - mainly because age changes with change in the year

Also, how many people having age ≥ 75 yrs are there in 2013 and 2014? Also, what percent of those people do NOT use internet?

No information is actually given about these - Doesn't look a valid question to me

This is literally all of the info given in the problem. The source is a prep course of a business school in Europe.
