Bring what upon people? The OP is asking about Windows 7, and I've only commented accurately and honestly about it, and about some attractive differences it has with Win 10. Don't get pretentious and arrogant.
Windows 10 has telemetry and data-collection which spies on activities and sends the data to MS, and so that's spyware. It has in-OS ads, and so contains adware. It has a lot of extra services preinstalled that could be considered bloatware, like Groove Music, Windows Store, Skype.
Both Windows 7 and 10 are essentially running on the same kernel, and the day when Windows 7 no longer works is probably the same day that Windows 10 no longer works. The two OSes are more identical than they are different, but many of the differences are worse on Windows 10 than in Windows 7. Saying "You should be thankful you can still use it" shows a lack of understanding from you. Windows 10 is mostly a repackaging of Windows 7 and 8, with lots of monetization features built into it to earn MS money whenever a person uses it without disabling all that stuff.
And Windows 7's start menu is better than Win 10's, as Win 10's reduces its functionality, not letting programs be pinned to the start menu - only in the live tiles.
That argument is lacking sense. Windows 7 is cheaper because it's older, not because people necessarily want to get rid of it due to Windows 10 being something great. Also, saying "nobody makes anymore Windows 7 keys" is silly, because Microsoft is the only company who makes Windows licenses, and Windows 10 is Microsoft's latest OS, and therefore is obviously the OS that they're going to be selling.
Microsoft has stopped selling Windows 7, not because there isn't an interest in it, or because it doesn't run on modern hardware (it runs anywhere that Win 10 does), but because Microsoft wants people using Windows 10 because MS makes money from people using any of Win10's services, and from the telemetry and data-collection of the OS. Likewise, Microsoft isn't forcing Win 7 and 8 PCs to install Windows 10 because it's helpful for the owners of those PCs, but because MS is trying to maximize their profit, with consideration for the customer being a distant priority of theirs.
'Not supported' doesn't mean it won't run... it will still run. But Microsoft won't back-implement utilization of new CPU technologies into Windows 7. That's all that it means. MS DOS doesn't have specific support for any hardware made since before the year 2000, but it will still run on all x86 hardware released up till now.
