Possible reasons...
1) Some here like to rant and rave on Apple no matter what
2) Some here have had false expectations with the new M2 and when that didn't pan out, they feel Apple let them down. Logical fallacy chasers can never be satisfied.
3) Some here are followers of the YouTube benchmark brigade / click-baiters. And no amount of common sense or fact will deter them from continuing on with the scare tactic storyline.
4) Some here are too nerdy for their own good, as they believe benchmarks are the alpha and the omega when determining whether to machine is worthy of being talked about much less purchased. These users can easily picked out of the MR crowd as they are oft to maker pronouncement of usage ability and outcome from a machine they haven't used.
5) Some are Innocent MR bystanders who have allowed themselves to get caught up in the forum / internet fray, instead of doing their own research and seeking out possible guidance from other members who aren't posting hyperbolic drivel just to get a rise out of people etc.
6) Some here knock on the M2 because doing so helps them to justify why they don't need it, And if they don't need, others shouldn't need it either. After all, one size fits all in MR land (or does it)?
7) Some secretly want the latest Mac toys but, they can't really afford it so, they make sure everyone else knows on a regular basis just how bad the extra $200 is (depending on location it may be more). These people can be easily spotted by their rhetoric of the M12 MBA was $999 so, Apple should give us the lasted tech and design for the same price.
8) Some here just like to be bellicose.
