I'm starting to get tired of being complacent about the fact that I am using Google's services when I'm well beyond the 'reasonable doubt' phase of Google being evil. They're a giant monopoly and I want to stop making them money as much as I possibly can.

Thankfully, I'm not as badly intertwined with them as I could be; I have already downloaded all the music I bought from them and since I have switched to iPhone, I'm not reliant on too many of their services. They do have some of my old files and pictures, but that shouldn't be too hard to get out. The biggest problem I can see is my email. Right now I'm actually paying $4/mo for an Amazon WorkMail account for a failed venture (which I'm planning on getting rid of), but I'm sure there are much better alternatives out there. I'd prefer something that has good spam filtering options including custom filtering. I was also wondering if anyone would recommend Apple's email service since I'm already paying for iCloud+ to store my backups.

Another more specific recommendation I need is for a replacement to Google Authenticator that works on iPhone. It looks like there are several options but I'm frankly not sure how to evaluate them.
