Indeed I feel the same all the time:

I do the more less the same as you, the bare minimum of protecting my data that would actually have any impact at all (banks, whatsapp, etc.) and nothing bad has ever happened -- I'm yet to see what will happen if my email gets leaked someday (if not already!) by any EvilCorp

But there are still people (eg, the main comment, as of this writing, by @kleiba) telling you about WHY we you must deGoogle ASAP, avoid using any social network to cross-login, etc.

Go touch some grass mate, life is too short to worry about what your local ISP will or will not do with your "data" (we do are a number in the end in this society)
