I don't get the point of this.
Since when did Sync masquerade itself as FOSS?
Just use whatever you want. Isn't that why we're all here?
Is the Sync noise getting to you? Just ignore it. It's natural since the app just opened up and there were a significant amount of Reddit refugees that badly wanted their app back.
I truly wish to see the day when any computer can easily run Linux painlessly.
I think the easiest ones I've seen are Linux Mint and all the vanilla installs of other mature distros, but I still see cases from time to time with friends and strangers who still somehow manage to get their setups in some issue or another, whether it's their hardware's fault or factory defaults / configs getting in the way or their own.
I'm just glad that these are getting much better than ever as time goes on.
