Lol, strawman argument much?
This is Github collecting usage metrics for their text editor. It should be fairly obvious to any programmer why they're collecting this information - it's to improve the product (which they will probably then sell).
The other thing is, Github is doing this in aggregate, and de-personalised.
But can you think of a single reason why a company like Github would want to collect, as you say, my password information, or webcam shots of me?
Apart from the stupid amount of bandwidth and storage they'd need to transmit and store webcam footage from all their users - what exactly could they gain from this?
What's the business case? How exactly would it make more people pony up money for Github subscription?
Since that's sort of their goal - to make money.
People seem to think there's some grand Illumati global conspiracy going on. There really isn't.
It's actually a lot simpler - this is capitalism, and companies exist to make money (within the bounds of the law).
If it makes them money, they'll probably do it.
If it doesn't, and it's "evil" they won't just do it for kicks of being evil. There needs to be a business case.
Somebody has to justify to their manager, who will then justify to their manager, why something will add value. Surely you've experienced this?
Now, I draw the line at the law, really - so if companies are fraudulently charging things to my credit card, or threatening to shoot me if I don't buy their product - yeah, that's illegal and I don't like that.
But if they're operating within the bounds of the law, or even if they're just being annoying and shoving ads in my face, I'll either put up with it, to use the service, or just use a different service.
As I said in a parent comment - the government is a completely different kettle of fish. However, companies are pretty easy to see through - their motives are, at least on a general level, pretty well defined.
