Mostly because they have been led to believe it will. "Yes, you can use a higher wattage charger with a device which requires less" is pretty common, even from PSU manufacturers.Folks appear to see 65W > 27W and assume it will just work.
Don't know about what the manufacturers are saying but I've only said similar things in relation to amps and a fixed voltage supply.
I think the misunderstanding is due to USB PD and Joe Averange not understanding how it works; not understanding what Watts actually are and their relationship to volts and amps; assuming that all USB ports and devices operate at the same voltage all the time (because prior to PD they did); and a beilef that more is better*.
It doesn't help that the matketing folks have decided on Watts as the unit of choice for PSU specs either. But, realistically, what else could they have chosen? A long list of V and A specs doesn't make for a short product name and doesn't make it easy to bamboozle Joe Average that my PSU is better than your PSU.
Yes, mostly. But I believe it's an issue with how USB PD is marketed not just with Pi though it is more obvious given the Pi5 only accepts 5V**.The mistake IMO is not in having done it, but not better explaining what was done, why, and the consequences of that. They have simply left people to discover their, not unreasonable, expectations were wrong.
*: Though most understand that more volts is bad.
**: +/- a small percentage
