Cons
Con Proprietary
Being proprietary, it's harder to audit.
Con Has some risky attack vectors
The only really good thing it has is that data is self-hosted (i.e. hosted on a server running on your machine with data that are on your machine).
- If user opens a malicious website that website may create users to access your data ("When registering, http traffic for creating new user on loopback http://127.0.0.1:8888")
- GetSync.com server receives many (all?) hashes in cleartext when sharing the directory.
Con Pro version for a fee
Selective Sync only available in Pro version. Business use is not allowed with free and Pro versions.
Con One peer of your network always has to be online to propagate changes to the other peers
Con Android app drains battery fast
Con No official client for Linux
Google as of yet has a client for Linux, leaving many who use the service forced to use third party apps or the webpage.
Con Data privacy not guaranteed
Data privacy is widely known as one of Google's weaknesses. Data shared through Google is most likely matched up with the user's profile inside other Alphabet inc. subsidiaries, and, due to the business model, used commercially.
Con Terms and Conditions allow Google to own anything on Google Drive
They can create derivative works, they can perform it, they can modify it, and they can publish it at will. There are many other specific rights they take over your product. Read the Terms carefully and compare with ANY others.
Con Very unreliable
Desktop client constantly crashes.
Con No WebDAV, FTP or SFTP
It supports none of these common protocols used for access to network storage, which severely limits OS integration. You are forced to use the browser or a standalone client, which isn't possible on all systems.
Con Low bandwidth
Can't even upload all my files to this
