Re: 1 in 6,500 real time snooping
Some dodgy numbers there
If they can intercept 1 in 10 000 ...
10 000 * 6 5000 gives 6 500 0000 users only in UK
Which seems quite small number of people ... although obviously there will be some shared use of landlines so one landline can snoop on multiple folk, but, as Alain said, multiple users of landline can be offset to a reasonable degree by mobile internet usage
The internet was used daily or almost daily by 82% of adults (41.8 million) in Great Britain in 2016, compared with 78% (39.3 million) in 2015 and 35% (16.2 million) in 2006.
(worth reading a few lines of that just for depressingly high (IMHO) internet Smart TV number)
