Why didn't more women side with Amber over Depp?

Because women are jealous of her.

Because women are jealous of her turd laying ability.

As I recall, initially they did. Depp lost his career there for a while. Jack Sparrow was dropped from any future Pirates of the Caribbean movies, and Depp was replaced as Grindelwald in the Fantastic Beasts franchise. Heard's claims were taken seriously for a while there, and it did real damage to Depp's reputation.

Then, as more of the truth came out, Heard began to look more and more like she was totally unhinged, and most women, I suspect, will not side with a woman for no other reason than that they both have no Y chromosome in their DNA. When the man begins to look more like he is the aggrieved party in the matter, fair-minded people of either sex are going to support him instead of the woman they see as his abuser.

Same reason black people didn't believe Jussie Smollet. They know bullshit when they hear it.

It looked to me like men and women alike supported whichever one they like best , rather than whichever they thought was guilty .
And not just in this case , many others , like OJ for example

Its scary to think thats probably how jurys work

I didn't side with either one of them because I think they are both shitty people.

Why would they? Women dont side with other people over any reason just because they are women. Its that woke crowd think they are but real people dont do that.

1. No one knows Amber Heard. She was not some popular actress. She was his golddigger with zero star power.

2. Just by looking at her you can see that she is rich privileged pretty face. Women dont like those.

3. Nothing good and sincere about her appearance. All her look screams: "Privileged selfish narcissist who got everything because of her looks"

4. There was no serious allegation. All people saw how they both were slightly pushing each other because they are rich privileged idiots. It wasnt like he beat her up severely or graped. Then women would look otherwise.

5. Most important - he is that young goldigger who slept her way into his bed and forced him to dump his aging partner, mother of his children. And no woman likes it. That was the main reason why no one cares for struggles of mistress basically. She is that evil witch who used her youth and prettiness to steal someone husband. Why would any woman support that person?

Same reason women didnt side with Angelina Jolie. By many she was still looking like a young hot chick who took away Brad from not that great looking Aniston. And then was like: "No, he is baaad and hurting me". They were like: "Well you stole him why complain now. Eat what you stole". And that thing that there were no serious allegations and she took away kids from him for no real reason.
