I have noticed that people on this instance are interested in deGoogling, so I wanted to share this email service that caught my eye. I'm seriously considering getting the Team plan and sharing and managing it amongst my family.
I'm glad Cloudflare works for you. Working with tried and true services is definitely an improvement on security, and there is a risk with using lesser known third-party services. However, I personally don't want to use Cloudflare myself given their questionable history, including excessive censorship. I look for alternatives to Cloudflare, such as DNS.SB for my DNS resolver. I am willing to support smaller companies and organizations as the benefits outweigh the risks for me, personally.
Yeah the deal is to use open source stuff cause it tends to be more aligned wirh our philosophical stance, so whenever people state open source as an upside understand that we'll go to through a lot to avoid proprietary stuff
