They can do a bad thing, and then you can make fun of it with an insult.
Own it, the insult is warranted, why hide and pretend it's not an insult.
If Microsoft is consistently shipping slop, then they deserve insults over it; not every "bad" thing is always unwarranted. Locking someone in a box is "bad", prison is a necessary thing that benefits society. Insults are "bad" and sometimes warranted.
It is supposed to indicate Microsoft cares only about money, which to me too, seems in the same league as microslop, i.e. mildly insulting but really not rude enough to be worth censoring.
And other insults are just words as well. It's the intention, history, connotation etc. behind words that give them meaning. M$ is meant as an insult, hence it's insulting. https://en.wiktionary.org/wiki/M$
