True, though I still think it's preferable to use for business, purchases, and logins. If I'm using an email besides Gmail, at least it means that I have a shot in that Google won't immediately know that I signed up for X service or made X purchase. Sure, they probably can figure those things out in other ways, but I'm not going to willingly hand everything directly to them.

Part of the reason I use Protonmail(and pay for it) is because I want to support the notion that the web can be made up of different services as opposed to all being calls to .google.com or .facebook.com.
