Considering the widespread misconceptions about condom efficacy rates, that they've made a decently effective alternative more affordable is excellent news!
If you are not familiar with the misconceptions, I will briefly explain:
The condom boxes say there's a 2% failure rate. That's 2% per year. Considering that most people are sexually active for far more than one year, that 2% rate is completely meaningless.
Furthermore, that's for perfect use. The actual way people use condoms, the rate of failure can be (an average of) 15% per year.
I tried finding studies on condoms that ran longer than one year, but couldn't find any. However, a survey was done that gives us an idea of the aftermath of this:
“Three hundred four women (78%) had used condoms for an aggregate total of 1178 years (average=3.9 years per woman; range=1 month-25 years). Seventy-eight women (25.6%) reported becoming pregnant while using condoms”
In not even four years, more than one in four of them became pregnant.

Unfortunately, this information is likely to cause anyone reading it to be at an evolutionary disadvantage, therefore it may make sense to spread the word as much as possible and remember to tell people who are dissimilar to yourself.
The condom boxes say there's a 2% failure rate. That's 2% per year. Considering that most people are sexually active for far more than one year, that 2% rate is completely meaningless.
Do people actually interpret that 2% to mean 2% per lifetime? If I didn't know what it meant, I'd interpret it as 2% per intercourse.
P/S/A: There are single sentences which can create life-changing amounts of difference.
