In one post they're complaining about things like Apple having the search bar in different locations in different apps, and in the next post they're seriously trying to tell us that a laptop that requires modifying the software and running shell commands copied from the internet so you can run a text editor to change settings and drivers is the solution? They dropped a note about how they haven't actually tried development on the chromebook at the end but say they assume it would be okay. For someone telling us to switch to Chromebooks, they haven't even finished doing their own homework
Linking to an SEO spam website called technical.city for performance comparisons is another clue that this choice was driven by something else first and the reasoning was backfilled. The new MediaTek part is fast, but there's more to laptop performance than a single bar chart from a site citing ancient benchmarks like PassMark.
I can't read this as anything other than an attempt to make a contrarian choice and then present it as the superior alternative.
