Is it correct to say that each new version of macOS is more demanding for the hardware and therefore, slows down the computer after each update?
Maybe, maybe not. While newer OS versions may require more resources, they are also optimized. It's been by experience that some newer versions have made my 2011 Mac Mini run faster and smoother than previous versions.
It's also majorly dependent on what is running on the computer besides the OS update.

I remember I had a MacBook black and it ended being really slow with the last version of macOS, even after doing a clean reinstallation of the system.
Hence my question: when should you stop upgrading to a new version of the system (regardless of functionalities gained or lost)? Is it advised?
In other words, do new versions of macOS make a Mac slower or faster?
New versions may slow down a computer, but in general a well kept machine should not in any way be subject to a crippling slowdown from an update. Also depending on how much RAM the computer has it may cope better with the new OS.
In general, its recommended to update to latest software if only to receive security patches and vulnerability fixes.
If a computer feels extremely slow after an OS update, then something else may be going on.
Note that generally, soon after an update the computer may be doing a lot of clean up, and will seem sluggish for a while. This should pass shortly however. Also many Anti Virus apps will attempt to scan the drive for threats after an update due to the many changes and that can also very much slow down the computer. It's generally suggested to not have Anti-Virus apps on a Mac as they are known to adversely affect the computer's performance. Macs are already very safe without them.
