Or is it just that their NSFW freedom of speech isn't significant because it's not to the benefit of a billionaire that these politicians happen to like.
That campaign to ban porn never really ended AFAIK, but my impression is the priorities of the party really shifted about 10 years ago to the point it's no longer an open policy (the word pornography no longer appears anywhere in the Republican party platform [1])
Remnants of the anti-porn part of the party can certainlystill be seen in the republican party, eg: Mike Johnson extolling his use of "covenant eyes"
Thus the arrow is flipped. The anti-porn cause was very active against printed pornograpghy and continued into the internet age. A right-wing/conservative movement and efforts both predating the internet.

I think all those factors combine to make them have to be kind of politically neutral.
In contrast, right wing views these as problems to be solved also with the legal system. Ban entirely and enforce with police and criminal sentences. Thus the "hates" I don't think is quite equal between the two.
I will concede for sure though that if you go far enough left the degree of 'hate' levels out between right & left, but the number of people on the two sides is different.
The "silent majority" part of the right wing, the old Reagan coalition for a long time was a pretty sizable part of the Republican party. Meanwhile, the twitter left progressive wing of the Democratic party is not as large compared to the republican religious-conservative right.
If we think to the OG far-left hatred of porn - that was there before revenge-porn etc were even concerns. Those OG left-wing concerns that did want to ban porn - were concerned about how porn disempowers women, can glorify violence, further genders inequality, etc..
As a general left/right difference, the approach is not equal. In the cases where the approach is to ban entirely - there are just different numbers of people in the far left "porn should be banned" camp compared to the "porn is sin" camp.
Sure, they technically didn't use the legal system, they just used the technicality that payment processors hold the same power over internet-dependent companies as a government.
I see those people as on the moderately far left, at least in the United States. There are plenty of people on the moderately far left who are not libertarian in the vast majority of positions, but who would agree in the case of drugs.
> Are dedicated porn sites like PornHub and friends considered somehow left wing?
Not directly no, but since the overlap between right-wing and religious (mostly Christian) are so significant, and many right-wing Christians believe that there is a spritual war going on and that porn is a sin/evil, and it can lead to atheism, and atheism is so frequently associated with left-wing, I think there's some consideration there.

I'm sure that's a factor as well. No (or very, very few) politican of any ilk is going to stand up for Big Porn and risk becoming the porn candidate. Personally I'd sure love to see them at least stand up for Big Porn in the name of free speech, but I'm not expecting it anytime soon.
