Not to threadcrap, but I am curious what people think about this. Over the years I've seen a lot of developers take none open-source code, or private JSON data strings and paste them into random sites they find searching "json format" on google. Does that make anyone else cringe? Is there anything we can do about this? Or is this just not a big deal and I shouldn't worry.
Aside from that, this is one area where web-based applications excel: You can inspect and limit what data an application is sending away about you via your browsers built-in dev tools and extensions like uMatrix (or your own request-filtering extensions).
