What are your forgivable sins?

The user @trim posted an interesting question in ~Tech and it made me wonder: what are my forgivable sins? What kinds of misdeeds on the part of companies that are suppliers of goods or services do I tacitly concience or to which I will turn a blind eye?

Whenever there is a scandal, the easy answer is, "I don't know, but definitely not that." This, however, is just an ad hoc definition that can be applied to any unsavory revelation on the part of a service or product provider. What would I be left with? I couldn't retreat from society if I wanted to and the cost of commercial puritanism would be prohibitively high.

What I realized in that topic was that (1) I will not sanction providers merely for doing business with others to whom I am opposed and (2) I will not sanction providers merely for issuing words or statements that I disagree with.

That said, I'm curious about others. What are your criteria for bad behavior in a service or product provider that you would judge to be nonetheless admissible?
