I wish I had as few problems in my life as you because I would never consider saying "I'm not using this because it's not open source" to be "slamming" or "disgusting".
The quote was to be exact: "Into the trash it goes". A cheap dismissal for arguably nonsensical reasons given that it's closed software specifically for a closed OS.
And let me add that this kind of attitude towards hard to make, well written desktop software makes me think people like you and the OP deserve every single one of the online-only Electron monstrosities on your desktop.
