"a far inferiour problem"
There is actually no difference: it has the design of a data collection silo
which, as mentioned in the blog post, is one of the two things that made mass
surveillance possible.
"Using third party services that sell them out" doesn't just refer to cases
where the service provider is doing that but is generic enough to refer to
any time where that happens.
With the current design they're just one letter away from the top five
intelligence agencies having full access to their system. The data of fifty
million people and an additional one million each week present a pretty
attractive target so who knows - maybe they've already received that letter.
That's the problem: Under current laws companies are forbidden from saying
that they've received one and thousands are issued each year. A notable
company is fighting that but that's really fighting the symptom and not the
problem. The real problem is using centralized services. Actually, the real
problem is the spying which people need to fight with their legislature to
address, but a second prong of attack can be applied by not using such things
in the first place.
