PETA does not advocate veganism as a moral baseline and also their undercovercover investigations are problematic:
"Using the Land-o-Lakes investigation as an example, we see that PETA’s blog report on the investigation emphasizes how important it is for Land-o-Lakes to “buy milk only from farms that meet our 12-point animal welfare plan, which would prevent much of the suffering we documented at this farm.” PETA’s 12-point animal welfare plan reads like an industry consultant’s quality control recommendations and refers to industry’s own standards and literature (e.g. Elanco Body Scoring Chart for Dairy Cattle and the American Veterinary Medical Association’s AVMA Guidelines on Euthanasia). 
Does PETA suggest that people go vegan? No. The blog report states “For those of you who can’t stomach the thought of eating butter after watching that video, take a minute to tell Land-o-Lakes to implement our 12-point animal welfare plan. Then check out one of the many vegan butter alternatives that are widely available.”"

PETA's approach is counterproductive and supports 'happy exploitaiton'.
animal organizations do undercover investigations, claim to have
uncovered "animal cruelty," and celebrate when individual employees
plead "GUILTY!," they imply to the public (99% of which consumes animal
products), that there is animal use that is "cruel" and animal use that
is not "cruel." They imply to the public that justice has been served
when justice will never be served for animals until they are no longer
exploited and killed.
put, we must shift the paradigm from the idea there are individual acts
of "animal cruelty" in the animal use industries that exploit and kill
110 billion animals per year to the idea the animal use industries
themselves must end by removing the demand for animal products by
creating vegans. The animal use industries are a monstrous
conglomeration of billions of individual acts of "animal cruelty." And
the problem is not the supply; the problem is the demand.
