I am doubtful they "chose to appease the FFA" as opposed to choosing to appease their profit margin. I think this decision was an economic one, not a religious one on behalf of Lowes.
FFA is known for advocating boycotts. FFA has in the past or is presently boycotting Snickers, Disney, Marvel, and a few others. On this occasion, FFA e-mailed its members to contact Lowe's and advocate the company rescind its advertising for the show. Apparently, a sufficiently large enough number of people did contact Lowe's requesting they pull their advertising to cause Lowe's to be concerned enough to rescind their advertising of the show. Lowe's then made a statement. "Individuals and groups have strong political and societal views on this topic, and this program became a lightning rod for many of those views," the statement said. "As a result we did pull our advertising on this program. We believe it is best to respectfully defer to communities, individuals and groups to discuss and consider such issues of importance."
Lowe's was seeking to avert a boycott precipitated by FFA. They didn't choose to appease FFA as much as they desired to keep their profits from being reduced by a boycott.
