Broken keyboards shipped for years, "we didn't think about thermal throttling", "we have no working replacement for a widely used professional machine", and "hey, here's this half-assed redesign that we still can't properly fix after release" have nothing to do with either commercial success or meticulous planning.
You know that "meticulous planning" is supposed to include mechanical tests, catching edge cases etc. right? Instead, it persisted for 5 years with minor acknowledgements and minor changes.
It took them 3 years to put the "condoms" on, 4 years to add additional caps.
3 years after release Apple started offering free keyboard repairs to all users with a butterfly keyboard.
All that for a "meticulously planned" keyboard whose issues were immediately apparent within weeks of release.
