Proprietary tools just aren&#x27;t worth the turnover for me.<p>It&#x27;s untenable to depend on developer tools that a company owns. I love free software, but in all honesty the reason I incorporate it is more selfish. My workstation is exclusively free software so I don&#x27;t have to be abreast of business news to get my job done.<p>I&#x27;ve basically settled on my emacs + notmuch + offlineimap solution not because I think it&#x27;s better than all email clients -- but it&#x27;s the one that if all parties involved quit, I could probably use it for another 10-ish years.<p>For example - offlineimap right now still has this old bug where sometime it uses all my cpu (and a bunch of memory) in some sync case. Ok, I don&#x27;t have time to debug this. I set limits and have it be killed when that state occurs. Annoying? Sure. Have to configure whole new mail client? Nope!
