Rather than handing over your details to an unknown third-party, why not make use of the projects published by Raspberry Pi themselves, here:
https://projects.raspberrypi.org/en/
Or read the freely downloadable archived issues of the MagPi magazine:
https://www.raspberrypi.org/magpi/issues/86/
(Although it wasn't directly your question, there is no indication that the website you mentioned is in any way connected to the Raspberry Pi Foundation. And the fact that the information is 'stale' - no mention of the nearly 4 month old RPi4b - might mean that it has been abandoned?)
