There are good closed source softwares out there but most of the popular closed source software are bad not because of their functionality but because of evil and controlling monetization tactics
WinRAR -s, honestly I haven’t paid for anything since I switched to Linux because everything is open source or freemium not that I paid for anything when I use windows anyway I quacked almost everything but I did bought Terraria and Half Life series
From my experience Windows have this system program called “CompatTelRunner.exe” that run silently in the background maybe once a month it’s send data to M$ and using a lot of CPU power while collecting data, now with Al being pushed to windows who knows what it could be doing in the background without user knowledge
LOL I don’t know who that is, but when I found this artwork on Wallheaven after scrolling for an hour I thought she’s pretty cute and she probably the type who use Arch on daily basis
