• Do not charge when conditions are too cold. Allow the car to precondition the battery first
• Do not charge when starting below 20% Charging the battery below 10%, (not 20%) will have the battery charge slow at first, quickly between 20 & 80%, then slow again from 80 - 100% unless it is an LFP battery, in which case, do what you want
• Do not charge past 80% The battery charges slower between 80-100% It is advisable to charge to 100% prior to taking long trips
• Do not charge too frequently. Patently false
• Be prepared for a stay at your charging station five to ten times longer than a typical gasoline fill-up, possibly longer if there is a que If charging from 20 - 80% the amount of time it takes ranges from 20 - 40 minutes, depending on the speed of the charger and the size of the battery

When is fast charging more likely to cause damage?
There are several times when fast charging may have a bigger impact on your EV battery.

Avoid fast charging in extreme heat without preconditioning your battery. Preconditioning is when the car’s thermal management system pre-cools the battery so it can accept a higher charge rate without overheating. Typically, if you set your car’s navigation to a fast charge station, the battery will be preconditioned.
Similarly, precondition the battery before fast charging in extreme cold. Often, driving a bit before fast charging is enough to warm up the battery, or get to the fast charger using your car’s navigation.
Avoid fast charging your EV at very low states or very high states of charge, since battery resistance will be higher.

Yes, there are mitigations, but there is no escaping that fast charging reduces the lifespan/capacity of your battery and consequently reduces the equity/resale value of an EV.

Well, you conveniently left out some very important information that they included, like anything about preconditioning the battery before charging. This happens pretty much automatically in cold and hot conditions.

I’ve added back in on some of your original points the things that you left out of your original list.
