I don’t know how you can follow web development and say Mozilla is a slave to Google. They go against nearly everything Google proposes. I get it that Mozilla makes money off of Google but in practice they are anything but slaves.

None of your workloads will require anything from the GPU so I doubt you’ll experience much, if any, throttling. That said, that means you are also paying more for the GPU in the M2 Max that you won’t be using vs the M2 Pro.
