It's really not strange for women to own a few plushies, but even barring that, squishmallows are just vastly superior pillows that also happen to be adorable. Women owning cute things? Women owning... PILLOWS!? SAY IT AIN'T SO, JOHNNY! Next thing you know, those wymmyn folx will be buying other crazy no-adults-allowed contraband like chocolate, fruit juice and scented candles. Dude's just jealous because women can own a few of them with no need for shame, but it's an actual red flag if he were to own one. Tell him to either stay mad, stay jealous and project harder or get over it. Or troon out, IDGAF. His loss if he's enough of a weirdo to avoid his only shame-free access to these glorious clouds of comfort while also increasing his odds of staying single.
Squishmallows of the actual pillow size happen to be the perfect size and shape to use as boob-protection pillows. I can't express enough how much I hate laying down on my side, only for the arm I'm not laying on to squish the boob on that side. It hurts, and normal pillows aren't always going to do the job. Just hold a pillow-sized squishmallow between your upper arms to prop up the one you're not laying on and it works great. If the one you actually want doesn't have enough stuffing inside to do this for some reason, just get the cheapest one you can find that you don't care about to use it for a stuffing transplant. The shiny, obnoxious rainbow ones don't really sell in my area, dunno about anywhere else.
As for their price, joke's on everyone else; mine came from Costco for $10 each for the big pillow-sized ones and $25 for one the size of a beanbag chair. Spending hundreds on one of those or filling one's dwelling with them is some batshit consoomerism. If I made the rules, scalpers would be publicly beaten before going to the stocks where they'd get bombarded with antisemitic slurs.
