Apple says "Less than 0.00673% of customers have been affected by government information requests." That's approximately 1 out of every 14,000 -- seems like a lot to me!
I'll give you P(spy) = .01, which feels plausible, around 140 incidents, but we have zero evidence. For something like P(spy) = .1, 1400 requests, I'd want more evidence. It dosn't need to be particularly good evidence, because i don't hold the NSA side to be particularly good.
But, you know, still more than vague comments about the state oppressing a vast number of people with undocumented shady tactics. They've been proven to use undocumented shady tactics in the past, but they also seem pretty bad at keeping that stuff secret for long.
Percentage is a convenient con used in some contexts.
