I take my privacy and security very seriously when talking about going online. I counted a lot of commercial products on my computer but I also have a lot of open source software too.
The words open, community, and cooperation accurately characterize the open source software community. It is nice to use open source software because you can easily review the code and many people do to see if anything malicious is happening. Community and cooperation are needed for an open source project to work and are highly valued. The word open for me relates to freedom and trust.
When I hear the words “share” and “social data” I personally think of privacy. I think that our social data is not private anymore and that is a bad thing. So many companies like Google and Facebook are collecting our personal data to use for their benefit. One use is ad targeting.
Some web extensions that I use, that I reccommend others using to help with privacy are: NoScript, Privacy Badger, HTTPS-everywhere, and ublock origin (for ads).
