the moniker "Modified Sine Wave" is a misleading term, and should be
changed to "Modified Square Wave"

I would prefer "stepped sine wave". But I can accept the term "modified
sine wave" as marketing speak that has been on lots of UPS boxes for 20
years. (UPS itself being inaccurate for a standby power source.)

I believe "stepped sine wave" to be an oxymoron. UPS (uninterruptable
power supply) isn't so wrong, as from the computer's POV, the power
never was interrupted. Of course, we know the difference between
"online" and "backup".
