I resigned from Dropbox recently because they don't have a subscription that is right for me (I'm not a data hoarder who needs 1TB of synced space, I just need 50 or 100 GB max) and because (most importantly) added an artificial limit of max 3 devices sync for free tier.

I switched to syncthing and so far I love it. Now my data lives on 2 always online servers plus few laptops, vms.
