Reckon that's true (I mostly use Linux). Trouble is, Windows has such wide usage and large legacy that one often can't avoid it (some important commercial/industrial software just won't work under, say, Wine no matter how much tweaking and unfortunately there's no Linux version).
To me this is the #1 reason this looks fake - nobody uses Mail for Windows, it probably doesn't support the security features available in O365, feels totally wrong for someone at MS.
During the pandemic I built a number of simple indoor solar systems, setting panels in the lower part of my windows (I keep the shades open at the top) and hooking up to either a homegrown controller/battery/inverter system or a jackery.
The jackery is roughly 30% more expensive but feels a lot less fragile than my homemade stuff, and I've moved all my device charging (tablet/phone/power tool battery) charging over to these systems.
It was a fun project! Cabling is always the part that sneaks up on you so make sure to plan out the cabling / what plug types you want / crimp or buy / etc. ahead of time.
