Right so if you look at LEAP[0] they talk about how "global average consumption of meat and dairy is rising, driven by increasing incomes and population growth ... livestock production can have major environmental impacts ... Livestock production is also a major source of greenhouse gases and other pollutants, increases water scarcity in some regions and can exacerbate soil erosion ... LEAP programme aims to understand the health, environmental, social and economic effects of meat and dairy production and consumption to provide evidence and tools for decision makers to promote healthy and sustainable diets"
I'm not going to call this a nefarious conspiracy, but in the same way you might wonder about a study funded by Coca Cola, LEAP doesn't sound like they'd want to fund a study concluding "eating beef is much healthier than soy protein"
If you combine that with the original criticism about the poor study design, you can come to your own conclusions about whether to reduce your meat consumption.
They also have a brief explainer video: https://www.youtube.com/watch?v=DGpjeyypKMU&feature=emb_logo
