Actually I’d be glad if I were you. Getting ads and “jmail” for stuff you are not interested in at all means that at least those fishy ad companies do not have enough information about you to tailor their spam to your wants and needs.
That being said, I second everything that’s been said about email so far. I do not, however, agree with the medium post mentioned above. I realize it is deliberately written in a very polarising way but there are so many ways to not use google or its services - even though of course it is almost impossible to avoid them completely.
I (still) use ddg for my searches, I use a VPN to browse the net, I use firefox with strict privacy add-ons, I use protonmail for Mails, etc etc.
Makes me not feel completely “secure” and “private” but it makes me feel like at least I try to not throw all my informatino at their feet…
Also, I just found this in a protonmail blog post regarding their 4-year-anniversary:
We also remain committed to building Proton Calendar, Proton Drive, Proton Docs, and much more, so that we can provide a more private alternative to what exists today ( Source )
