This kind of thing would be real news in...2005. In 2021 unless you go extreme low end Chromebook territory, it's very common for ~$600 Windows computers to come with 8GB RAM, quad core processors, and 512GB storage, and it's Microsoft's own stupid fault that the MINIMUM requirements aren't set high enough so that even the cheapest machine will be capable of a decent experience, because we have all seen those HP machines in Walmart for $300 that will be slow as daylight.
It doesn't matter how fast and secure an OS is, for a lot of people it has to look good, be intuitive, and "just work", something Windows 10 finally got to with 1901, and have a really good reason to upgrade. The fact that any machine not capable of TPM 2.0, which excludes a lot of still really snappy machines (especially those with Ryzen 1000 series hardware) means a lot of people won't want to upgrade because it means buying a whole new computer. For laptop users who have bought a laptop in the last couple of years, possibly to work at home due to Covid, if that laptop doesn't have updates for Windows 11 then they surely won't update. For many more people, myself included in this group, Windows 11 doesn't bring anything new to the table except a subjectively worse UI, so there's no reason for them to upgrade.
