I have one of these http://www.webcamerablocker.com/ on ALL of my devices with a camera, on my smartphones i've covered the cameras with a small square of duct-tape, on my laptops i've ripped out the microphone arrays or disconnected them and use the Mic input with a head-set if required.
I run my own mail server (although i hate having to email people @gmail.com etc) and i only store my emails locally. I don't use dropbox, i don't use cloud storage providers at all. When I have to upload things, I encrypt them first. I run almost everything through TOR, that includes all my web-browsing on my phone even.
There are a thousand ways that data can be collected about you these days given the technology we use, but I like to think i do a reasonable job at avoiding all of the bulk of them though. Nothing is perfect, but i'll be damned if i'm going to make it easy for anyone.
Might just be a cultural thing in Australia. Really not sure. That being said, in smaller office environments, the opposite is true i've found, everyone is very accepting and quite diverse both in gender and race without any cliques forming.
I work as a consultant and am at a different company more or less every week, as a result i've made a couple of observations.
As a temp/contractor, its hard to get to know people in an organisation when they know you'll only be there for a week, you might have lunch with the team one or two days, but for the most part, you'll spend a lot of your time on your own.
In larger companies (I primarily work in IT environments) that are more diverse (in Australia anyway), ethnic groups stick together and speak in their native tongues. I've sat and watched a group of Indian guys/girls chat in hindi in a circle over lunch, a bunch of Chinese guys sit and chat in Mandarin while a table full of Japanese people do the same a few meters away and the two white guys (who I don't know/haven't been introduced to) sit and don't talk. What's more, no-one interacted with anyone else at all outside of their little groups.
I personally find that really bizarre and I wish i could change it somehow but as i'm not even involved with the organisation other than as a contractor, its quite removed from my role.
