fighting against patriarchy benefits everyone suffering under it

So right from the get go, the language you use assumes masculinity or “patriarchy” is inherently broken and needs to be fixed. I find that sexist and imo a non sexist take is to free people from human greed and selfishness.

as women have needed and still need to fight for basic legal rights and autonomy

Yes! That’s when feminism made sense. It was named after women, for women’s rights, which they got. Feminism being a success meant it was not needed as much.

ones that are the reason why we all have a better society,

That’s is VERY subjective and I doubt you would get most people to agree that feminism made their life better. As I guy I can inform you that it has made my life much, much worse. I doubt you would believe me though.

Disregarding and diminishing all the efforts and benefits by nitpicking over the origin of the word just seems ungrateful and unfair.

I mean if that’s what you took away from my comment then you misunderstood. Feminism worked well for women, and I’m happy for them. They are the judge on what helps them and what does not. Same way women have that right, I have the right to state that feminism has made life better for women at the expense of men.

If there are women out there fighting for true equality, please note that if your truly fighting for men, you would use the terminology that communicates that the best, by not using the label feminism.
