TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.
And with that, hopefully we can put this argument to rest.

I think this accurate or close to it for phones but my laptop battery a Dell has degraded very quickly through 50 plus or more cycles of battery like 15 percent. It went from 59wh down to 50wh and it ebbs and flows. Runs Linux mint and installed power top and some other low power mods to help dumb things down to conserve. I feel like arm processors vs x86 are wildly different.
What kills the batteries is keeping them at 100% charge all the time, especially when the laptop is hot. Some laptops do have the ability to limit the maximum charge. Setting the maximum charge to 60-80% when the laptop is going to be plugged in for a while will extend the battery life. It is necessary to occasionally do a full charge to keep the capacity sensor calibrated though.
