Apple usually compares to last years model with many of their products, but lately they have switched this to comparing to models a few years older. I think this may have two reasons:
1) They know most people dont upgrade every year, so their marketing is targeted towards people who are upgrading from older hardware. Of course this is purposefully done for maximum impact, but it does help someone who is upgrading from a 2018 Mac mini to the new M2 see how it compares.
2) Apple is behind on their silicon roadmap. The pandemic I think set them back by a year or more. We should be on to M3 at this point: Fall 2020 = M1 | Fall 2021 = M2 | Fall 2022 = M3 and later this year we should have been seeing M4 in the fall. That would be if Apple and TSMC could keep an annual update cycle. Since they're behind schedule they are forced to use devious marketing to make their products look better than they are.
