Even open source is getting worse.
GIMP will stall for 10-15 seconds at startup looking for XSANE plugins. Apparently it's calling some external server, bad in itself, and that external server is slow. Worse, this delay stalls out the entire GUI for both GIMP and other programs.
There's no excuse for this "phoning home". Especially for XSANE, which is a rather bad scanner interface.
