I did a poll and nearly 30% of the people who voted said they used Sync! It's stayed around that percent the whole time too!
EDIT: Here is the poll I forgot to put this here like five times lol https://strawpoll.com/wby5A21R1yA
If you're not happy with the software there's a good chance others are also dissatisfied and van make the chage, this happens all the time. Perhaps some of them are children without a full time job and don't mind spending time understanding something ;-) The point I'm making is that the users of the software have an additional option not available to closed source software.
