This is taken from the Lowe's Facebook page today, and we like it because it's a good generic corporate apology that tries to explain a bad decision:

It appears that we managed to step into a hotly contested debate with strong views from virtually every angle and perspective – social, political and otherwise – and we’ve managed to make some people very unhappy. We are sincerely sorry. We have a strong commitment to diversity and inclusion, across our workforce and our customers, and we’re proud of that longstanding commitment.

Lowe’s has received a significant amount of communication on this program, from every perspective possible. Individuals and groups have strong political and societal views on this topic, and this program became a lighting rod for many of those views. 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.

We strongly support and respect the right of our customers, the community at large, and our employees to have different views. If we have made anyone question that commitment, we apologize.

Thank you for allowing us to further explain our position.
