Osama Bin Laden avoided electronic communication well before the NSA's illegal domestic spying activities were revealed. He passed notes and relied on trusted couriers. This is nothing but political opportunism.
The NSA had bin laden's sat-phone line in the 90s. I've seen documentaries on it.
Snowden confirmed the extent of NSA surveillance in 2013.
So that's 12 years for which the GP's statement was true.
