Re: Being sensible for a moment
My car was manufactured 15 years ago, and I have had recent cause to replace all the suspension springs on it, as well as replacing the cam belt and water pump at 100,000 miles. If the manufacturer of this car had told me that it was no longer supported, and that road springs were not available, and that they would not provide a new cam belt, after a mere 15 years, and I have to buy a new model, then I would rightly have cause to complain about this.
The car analogy really doesn't work in your favour in this argument. I can expect to keep it running until something fails catastrophically on it, that is not economical to fix, such as a blown head gasket, or a severely rusted chassis.
Similarly, I should be able to keep a PC running with the OS that I paid money for, as long as something doesn't fail catastrophically on that PC, such as the motherboard chipset melting. Like a car, I can replace individual parts as they reach EoL. Since I have been smart with the components most likely to fail, and bought decent quality ones from a manufacturer that offers a lifetime warranty, if something like one of the RAM modules fails, I can get it replaced. I have had this happen exactly once, by the way, in the last 30-odd years of owning and using PCs.
Again, like the car analogy, I might choose to buy new at some point, but that's a choice based on ageing hardware, not an OS one. Also, as with cars, we have pretty much reached the point in the development of PCs that any improvements are incremental, a new car offers an engine with pretty much the same performance as a 15 year-old one, and things like processor speeds and the cost of RAM in a PC have pretty much plateaued for several years now. I won't be buying a new PC just so I can use the latest Windows (my PC supports Win11 anyway, so this is moot), just as I won't be buying a new car just so I can use the latest built-in sat-nav, phone integration, or fancy HUD.
Microsoft's attitude towards no longer servicing Windows 10 is akin to a Ford deciding that garages can no longer service cars older than 8 years. I can understand main dealerships doing this (who in their right mind gets their car serviced by a dealership anyway), but if they inflicted this on my local garage, there would be a hairpiece from Hades (Hell toupée).
