This FUD has to stop. An 'unsupported' OS will not instantly get hacked. If anything, you should be safe doing what you do now unless you are pirating software or viewing porn or using Limewire (if it still exists). Even Windows XP has support for a few antivirus apps today. This mentality of 'you should stop using software that's old because it's a security risk' makes no sense anyway since any hacker really worth their salt will want to target a more popular and mainstream OS version that has more market share than target the 5% who still use XP or Android Cupcake.Well yes but also keeping things updated is quite important for security reasons and to be fair Apple has been good with such security updates for older versions of MacOS just as they are with supporting older iPhone and iPad models with the newer iOS and iPadOS updates.
Heck, many of those scammers who make those fake 'your PC has been locked by Microsoft' pop-ups are targeting Windows 10! Those popups won't even show on Netscape 7 or Internet Explorer 6.0.
