There seems to be concerns about the sustainability of the dividend. At present they are returning 39% of EPS to share holders. This is same as BP and a bit less than RDS (40%) and TOT (43%), and more than CVX (27 %) and XOM (24%). Looking at DIvidata, they appear to have a strong history of no divi cuts and consistent increases as far back as 1986 (25 years). As a dividend first investor, I am not yet concerned. Their spinoff of PSX will take time to digest. Any divi cut would be minor at worst. I am inclined to add to my position on any sort of dip of 5% or more. The current 4.5% yield in nice. This is just my opinion however. Your mileage may vary.
I don't consider Seeking Alpha credible and for that reason don't read any of the articles (bullish or bearish). Interestingly, it is the only news source Yahoo will not let you filter out. Basically, it's sanctioned spam.
