I don't think Apple is out to mislead anyone. This is a spec. bump with an improved CPU. In general computing scenarios, the claims are true this is an improvement over the M1. If I was shopping today, I would get this over the M1 all day long (but I would probably just get the Air if I was looking for a base machine).
Overall performance is better is better than the 13" M1 MBP. To most users, the difference will be barely noticeable from M1 to M2, both machines are very fast and responsive computers.
Remember, the real market for these laptops isn't people who have an M1. It's to those who are on Intel Macs or Windows PCs. If you have an M1 and it's too slow - you need something other than an M2.
Good point, if it was true, but for 99% of user tasks it is faster.
Look at every general performance benchmark and it is higher with M2. Sure, there are some specific benchmarks where the old machine's SSD configuration might be better suited, and if that's the case for you then absolutely go for the discounted machine. For everyone else M2 is the better experience and higher performance package.
