It is because someone holds a false believe(like an "out of date") and have a very narrow worldview in order to allow other concepts to help open it up.
Well said
My 2015 15" MBP, now on Monterey with an NVMe upgrade, is super snappy and flies through everything I need..
And I'm using Photos, iCloud, iMessage all perfectly
It may be "obsolete" according to Apple, but using it certainly negates that concept.
It worked fine on Sonoma also (w/ OCLP .. Apple macOS bugs not withstanding)
If Apple really wanted to, they could be supporting all these machines SO much longer than they do.
